How To Fix A Portable Generator

How To Fix A Portable Generator
4.25 | 20 votes

Ever tried to start up your portable generator only to be greeted by the sound of silence? Here’s How to Fix A Portable Generator.

Don’t panic. There are a number of quick steps you can run through before you dig out the receipt and call the professionals.

1.      Check the Fuel

We know; it’s like being told to check that the kettle is plugged in. But one of the most common reasons for portable generator failure is simply that it might not have sufficient fuel. Especially if the last time you used it was last year. As well as checking the quantity of fuel, be sure to check the fuel quality as fuel can degrade while in storage. If this has happened and it has clogged up the engine, you might need to call a mechanic for help.

2.      Check the Oil

Many portable generators feature automatic oil checks and will shut down automatically if the oil level becomes too low. Check the oil level with the dipstick and if necessary, add oil to meet the full level.

Check that the oil level is full

Check that there is sufficient oil

Also check to see if you generator needs an oil change. Within the product manual of your generator, the manufacturer will recommend the frequency of an oil change. Below is a good demonstration of a customer changing the oil on his inverter generator:

3.      “Field Flash” a Portable Generator with a Battery

Sound complicated? It simply means jump starting the portable generator (Note: only attempt this with condenser style generators not inverter generators). While in storage for a long period, the magnetism in the generator’s rotor can diminish, reducing its ability to produce electricity. A small current from a battery can quickly resolve this problem.

Field flash is a simple jump starting technique used in case a portable generator fails to start normally. Use a battery and connect the wires from the generator to the battery correctly (negative to negative, positive to positive, wires are usually colour coded). Remove the spark plug from the generator, and pull the starter cord to get it working.

4.      Check the load

One common problem is that a generator is overloaded and simply cannot produce enough power. Each portable generator is designed to handle a specific electrical load, which should not be exceeded. What many people don’t realise is that certain appliances draw more power when they’re starting up than when they are in operation. The generator might be able to power the operating load, but not the start-up load which could be anywhere up to five times higher. Solve the problem by removing some of the items temporarily. Add them gradually, waiting for one to settle into operating mode before adding another.

Test The Load On Your Generator

Test the load on your generator

5.      Replace Fuses and Circuit Breakers

If your portable generator is running but not generating power, it may have blown a fuse or tripped a circuit breaker. Resetting the breaker and replacing blown fuses will easily solve this. However, to prevent this from happening again, try and work out what caused them to trip or blow before restarting the generator.

6.      Generator Is Running But There Is No Power

If the generator is running, but you are not getting any power, chances are some internal setting or the motor might have been damaged. To check on this, keep a voltmeter and ampmeter handy. Find out what the correct readings ought to be from your generator user guide and check if the meters are giving a congruent reading. If not, then it is most certainly an internal issue, which needs the expertise of a professional to fix. So, call in the experts!

The best way is to prevent any issues from happening in the first place is to take necessary precautions and maintain your portable generator. Ensure that you do proper and timely servicing of the generator, even if you don’t use it all that regularly. Also replace any parts that might be used above and beyond their usual running life. And finally, remember to use good quality oil and fuel as they circulate through the entire engine coming in contact with many different components.

Still need help?

If you are still having problems with the generator or don’t feel confident going through the steps above, it’s best to seek professional help. This will stop you from further damaging the generator or voiding the warranty. For more information, contact the team at My Generator.

    Hi, my Inverter generator immediately says overload and won’t start.

    -Chris

    • My Generator Admin May 10, 2015, 11:08 pm

      Hi Chris, if your generator is signalling overload and won’t start, it could be a low oil sensor and you will need to check the oil level.
      If your generator is running but won’t produce power, it could be that the appliances you are trying to start are too big for the generator and the circuit breaker has been tripped (which can be re-set)…or your inverter board may be damaged, in which case you will need to take it to a service agent to be inspected; check your manufacturer’s warranty card for details. Hope this helps, cheers!

        My ryobi ryi2200 watt inverter dont want to start. And it says overload and wont start

  • Eddie Sweeney June 29, 2015, 9:49 pm

    Hi . I recently bought a hyunda 2000 si . It starts up on the 1st or 2nd pull . Problem is if I stop the engine , then try to restart it then it refuses to start . When I try it again the next day it again works 1st time . Any ideas .

    Thanks .

    Eddie Sweeney .

    • My Generator Admin June 29, 2015, 10:49 pm

      Hi Eddie, in this instance, we would recommend that you contact Hyundai Power Equipment to find you local service agent who can inspect the generator. Their Service Agent details can be found on this website: http://hyundaipowerequipment.com.au/
      Thanks, Steve

  • Sudish August 31, 2015, 4:12 pm

    Hi

    My generator was not used in a very long time and when I tried to pull start it, it does not start. I have tried to check but can’t seem to get it started. Please assist.

    Thanks

    • My Generator Admin August 31, 2015, 11:45 pm

      Hi Sudish,

      When a generator is not used in a very long time, often it wont start. There are several things that could be the problem. First, if it is a petrol generator, then the fuel may have gone ‘off’. You need to start the generator with fresh fuel and ideally fresh oil. You should also check the spark plug as this could need replacement. Other things to check are the air filter which could need cleaning or replacement, as well as the spark arrestor.
      You can read our FAQ page here which may provide additional help, or also watch this video: https://www.youtube.com/watch?v=4dwDsMRXJTE. If you still have trouble starting your generator, then you may need to take it to a local small engine specialist or approved generator service agent. Thanks.

  • Didas Erene October 4, 2015, 6:06 pm

    Hi, I have kibii 8kva petrol generator, earlier everything was okay but now when i start it, it runs for 1 minute then it display ‘prealarm, under frequency shutdown ” and then it goes off. please advise!

    • My Generator Admin October 5, 2015, 10:13 pm

      Hi Didas, unfortunately “Kibii” is a generator brand we don’t stock or know much about, except that they are a Chinese brand. For the kind of issues you are having, you would have to contact the dealer you purchased it from, or try and contact Kibii directly (if they have an Australian presence). Thanks, Steve.

    • Farooq Khalid Mughal October 13, 2015, 5:50 pm

      Hi Didas! Check you oil sensor. Remove your oil sensor connection and then start. When it runs try to connect oil sensor wire. If it goes shut down then your oil sensor is gone. Remove its connection permanently.
      Another issue is that check your spark plug . If it produces continue spark or not. Turn off fuel, remove plug and touch a wire with spark plug. See that it produces blue spark continuously or not.

  • Tamar October 12, 2015, 3:57 pm

    I have a Pulsar 1200 2cycle generator, brand new it starts up for a minute then it shuts off and this process just keeps repeating. It won’t hold its choke. Any advice on what to do with this. I must not be doing something right?

    • My Generator Admin October 13, 2015, 6:51 am

      Hi Tamar, we are not familiar with the brand or type of generator you have so our advice would be that you contact the retailer you purchased it from or take it to your local service agent for inspection. Thanks, Steve

    • Farooq Khalid Mughal October 13, 2015, 5:44 pm

      Hi Tamar! Check you oil sensor. Remove your oil sensor connection and then start. When it runs try to connect oil sensor wire. If it goes shut down then your oil sensor is gone. Remove its connection permanently.

  • Farooq Khalid Mughal October 12, 2015, 4:39 pm

    Hi, I have 2.5kw generator. Since two days I have clean the filter, spark plug and changed engine oil. After this my generator starts and then turn off. I have checked all connections. It give accurate voltages and also pick the load.

    • My Generator Admin October 13, 2015, 6:56 am

      Hi Farooq, given you have undertaken some of the key generator checks and it is still not working, then we would recommend you take it to your local service agent for a technical inspection. Thank you, Steve

    • Farooq Khalid Mughal October 13, 2015, 10:22 am

      Hi Mr. Steve! The local service agent are also failed to find a problem. Thanks!

  • Chris October 13, 2015, 2:07 pm

    Hey,
    Had the same issue. Turned out to be a vacuum pressure in the gas tank. Loosen the gas cap and try again. If still no improvement, spray with starting fluid until the fuel supply builds back up (keep spraying and tying to start it).

    -Chris

    • Farooq Khalid Mughal October 13, 2015, 5:54 pm

      The mechanic said, there is a problem in the engine head. 🙁

      • My Generator Admin October 14, 2015, 3:50 am

        Sorry to hear Farooq – I hope the mechanic can sort it out for you quickly. Regards, Steve

  • Diane Rivers November 14, 2015, 7:09 pm

    I have a coleman 7500 generator. I changed the oil and dumped out the old petrol and put in fresh with a little mystery oil spark plug, seems okay. New battery but in turning the key there seems to not be enough to get it revved up to start it kinda starts making a little noise so I back off it is like not enough energy for the motor to turn and get compression to turn I think the piston . I am not a mechanic, right now I am winging this for the technical part that I do know. Is there a reason that I am missing something?

    • My Generator Admin November 16, 2015, 3:04 am

      Hi Diane, it seems you have done a good job undertaking most of the basic checks. We’re not a retailer of the Coleman Generator range so aren’t intimately familiar with the specifics of your model and given you are still having trouble, I’d advise you to take it to your local approved service agent for inspection. Thanks, Steve

    • Farooq Khalid Mughal November 25, 2015, 8:37 am

      Hi Diane Rivers! Have you clean carburetor and Air filter too? If you don’t than do it, and check the choke.

  • Dan November 26, 2015, 2:52 pm

    I have a brand new Honda 6500 electric start. I just completed full maintenance on it having not used it for more than 2 years. I tried to recharge the battery with an 8 amp car battery charger and now the electric start is completely dead. I have come to realize that I should have only used a 1.1 Amp charger so I bought a new generator battery and still nothing. I know I fried something but not sure what. Any ideas?? Thanks

    • My Generator Admin November 26, 2015, 10:50 pm

      Hi Dan – bit of a tricky one. With battery charging, it is always recommended that you use a battery charger as the charge is then properly regulated… without a proper battery charger you run the risk of damaging the batteries with an unregulated charge. Now that you have a new battery and are still having issues, I’d be inclined to contact your local approved Honda service agent; they’ll be able to troubleshoot or perhaps inspect the new battery its functioning properly with the iGX390 engine. Cheers, Steve

    Hi I have purchased a 4.4kva Gentrax Generator as a back up on a small farm. Is there a limit to the time i can run this sort of generator?

    • My Generator Admin February 16, 2016, 2:02 am

      Hi Emmanuel, we don’t sell the Gentrax, but we have had experience with some of the budget brands from China in that size. We’ve tested them running a few fridges for around 15 hours continuous use (roughly 2 full tanks of fuel) and some brands stand up to it fairly well. When you start going longer than that, we’ve found there can be overheating issues on occasions. They aren’t designed for long term continuous use – only infrequent use up to a few tanks of fuel at a time. People do run them for longer, but again, its not what they are built to handle.
      If you want an inverter generator option around that size for longer run times, I’d suggest you look at the Yamaha EF2800I which comes with an 11 Litre Fuel Tank.
      Cheers, Steve.

    • Joann Stanger August 10, 2016, 6:21 am

      Hi Emmanuel we have the same one but have lost our manual is there anyway you could email me a copy please thanks for the assist regards Joann

  • Brendan April 14, 2016, 6:34 pm

    Hello,
    My Honda EU 6500IS Invertor Generator won’t start or turn over.
    The generator refuses to turn over from the starter battery or when being pull started. It only has a few dozen hours on it, if that. I just put fresh fuel into an empty tank and charged the starter battery. Oil level is good. Spark plug looks great.
    Pull starting doesn’t sound like it is getting anywhere at all. Starting with the battery doesnt turn over or sound like it is even trying to start.
    Could use some help. Thanks

    • Lachlan Adams April 15, 2016, 12:19 am

      Hi Brendan, thanks for your question. I’d double check the oil level to start with as the generator has a low oil sensor – this is a common problem that stops generators from starting. The other thing could be the fuel – was the generator in storage with fuel residue? If so, was a fuel stabilizer used? After those checks, I would then contact a Honda Service Agent if you are still having the issue – Here is the Honda Service Agent directory link: http://dl.hondampe.com.au/Default.aspx?d=P/E
      Cheers, Lachlan

  • Kieran April 17, 2016, 5:42 am

    Hi. I’ve been given a Gentrax GT4000. The engine runs fine (seems a bit loud & fast) but runs smooth.

    However, the overload light always flashes even with nothing connected & the power outlets turned off and when I connect anything there is no power output (12v or 240v)

    Any ideas?

    • Lachlan Adams April 17, 2016, 11:54 pm

      Hi Kieran, Thanks for your question – from what you have described, it sounds like there could be a problem with your inverter board. This can be a common problem with the cheaper Chinese inverter generators (like Gentrax, Fuji etc.) – the engine will start and run, but there is no power output. You could contact Gentrax to inquire about a replacement inverter board, but often the cost is prohibitive and it may be more practical to buy a new Inverter Generator. Hope that helps – cheers.

  • Shamir April 28, 2016, 7:03 am

    Hi i have a ryobi 1100 watts petrol generator and is burning spark plugs like in 2-4 days, can i get some help why its doing this?

    • Lachlan Adams April 28, 2016, 11:04 pm

      Hi Shamir – this could be many things; wrong plug, incorrect gap fitting, engine problem. Difficult to tell without inspecting. I’d be inclined to take it to a local small engine service agent that is willing to work on ryobi generators. Thanks.

  • Krystal May 21, 2016, 12:05 pm

    I have a pulsar generator and every time we pull to start, it turns on for a couple seconds then turns off. Need help!

    • Lachlan May 22, 2016, 11:46 pm

      Hi Krystal – sounds like it could be a low oil sensor, so check your oil levels. Or, it could be an issue with the fuel line – check that fuel is getting through properly. These two basic steps are a good starting point and can often solve the issue you are having with your generator. Cheers 🙂

  • Dan Imhoff June 6, 2016, 2:21 am

    Hi
    I have a Gentrax 2 Kva Generator for about 12 months now….its not missed a beat…I do however agree it is on the cheaper side of generators and is run as such. My question is this, I was running it on standard unleaded fuel all of its life from new, a few weeks ago I accidently put in 98 octane unleaded fuel and whilst this will make it run hotter it has developed a problem where if you choke it as normal it runs within a few pulls. However when I turn the choke off the engine dies…..would this be due to the higher octane fuel…(personally wouldnt think so). I took off the carbi and checked for blockages etc, it seems to me when I open the choke it gets to much air and dies. But when I again close the choke it seems to run close to normal……..Lost with this one….Dan

    • Lt. Lemming July 11, 2016, 8:01 am

      Hi mate,
      I was reading through the q & a’s here and saw that no one responded to your… dilemma. Did you get it sorted?

      If not, right it’s highly unlikely it would be fuel for two reasons:
      1. the general rule of thumb for internal combustion engine, (certainly with small engines) low speed/ idle is fuel, high speed air.
      2. I read a post else where that and some Americans and Aussies on youtube have suggested using premium brands of unleaded fuel works best with generators.

      May I suggest cleaning the air filter also check the inlet manifold for cracks and carb and carb manifold for cracks?
      It’s also possible as I write this that the higher octane fuel requires a different air – fuel ratio, which normally sits at 14.7:1.
      To combat this check in your manual (if you have one) which screw on the carb regulates the air flow, and adjust accordingly. It will however void your warranty (if you have one) so most “professionals” won’t suggest this.

      The other possibility is the spark plug isn’t up to the task, try using a blow torch (trust me a gas cooker doesn’t work too well) and remove the spark holding it in a socket, heat the pin (end of the spark plug) until it starts to glow red, allow to cool slightly, maybe one or two min, then reinsert the spark plug, then attempt to start with half choke, if not may need a better spark plug .

      Hope this helps

  • Asad Shah June 21, 2016, 7:20 am

    Hi,I have Hyndai Model #HGS 3500,is there any technical trick to lower it’s noise without effecting it’s engine life.
    2) I use natural gas which will lower its life but can you let me know the ratio of natural gas and petrol can be used to protect its engine life.
    3) Can we use any portable generator on continuous running for 2,3 days without rest?

    Your prompt reply will be appreciable.
    Warm regards
    Engr: Asad Shah

    • Lachlan June 21, 2016, 7:29 am

      Hi Asad, we don’t recommend making technical amendments to a generator as this can cause issues with the unit and void your warranty.
      Portable generators are not designed for continuous operation day in, day out. For this kind of power source, you would need to consider a diesel generator that runs at 1500rpm and is designed for continuous operation.
      Thanks.

  • Annette July 27, 2016, 2:05 pm

    My honda 8kva starts but the blue circuit safety switch wont stay on. Unable to use.

    • Lachlan July 27, 2016, 10:24 pm

      Hi – this could indicate that the appliance you are using is faulty and therefore the safety switch is tripping. If you have nothing plugged in and the switch is tripping, then you would need get the switch inspected by an electrician / service technician. Thanks.

  • Gavin Molloy July 29, 2016, 8:19 am

    Hi, I have a Gen Power GP-SDG6500S it’s a 3 phase unit and has been working fine using a distribution board connected to the 3 phase outlet. Last night it just stopped supplying power (volt meter shows zero when it is usually at 420) it did not trip the breaker and the diesel engine continued to run, I can still start and stop the engine and it runs freely. Could failure of the automatic voltage regulator cause this? Is there a test I can do to determine if the wiring has failed?

    • Lachlan August 1, 2016, 12:07 am

      Hi Gavin – it sounds like a possible issue with the alternator. From our previous experience with the Gen Power generators, this was not an uncommon issue. You may have to speak to the Gen Power dealer (edisons.com.au) regarding inspection. Cheers

  • Shah Rukh July 29, 2016, 11:36 am

    2 Months ago I have Purchased an Electric Start (Self Start) Generator. Since 2 days My Generator is Starting By Pulling The Cord But Won’t Start When I Use Self Start. The Battery and the Starter are in Good Condition. What Should I Do????

    • Lachlan August 1, 2016, 12:08 am

      Hi Shah – if it is not a battery issue, then sometimes the auto-choke in these electric start units can be causing issues. I would look at that in the first instance. Thanks – good luck

  • john Allan August 4, 2016, 9:10 am

    I have a Mishta X2500i inverter generator that runs smoothly when it is started but when I connect an electric kettle to it, the unit runs for about 15 seconds then stalls. Any suggestions

    • Lachlan August 4, 2016, 10:27 pm

      Hi John – we often get customers contacting us about issues they are having with a generator running their household kettle. The main issue is that a kettle actually draws more power than most people expect – an average household kettle will draw around 2200 -2400 watts (sometimes more), and will need this level of power draw the whole time it is boiling. So it sounds like your generator can handle the draw for a short period (the generator’s maximum peak capacity), but cannot sustain the required kettle power draw for a continuous (or rated) period. Thanks

  • Roo August 11, 2016, 9:20 am

    Hi, we just bought a kipor kde6700 ta for $200, it has a p-07 error code which is a charge fault issue, I put a multimeter on the battery when running and there is no charge going in so I figure this is the problem and was hoping you had come across this? it is a companion product and they are useless and have no real intention of helping me source whatever it is that is wrong… it also needed an oil sensor (P-01 error code) and it was easier to buy one in states for $63 delivered which was cheaper and faster than dealing with them (or through an authorised agent). For the money I spent it is worth fixing so any help would be appreciated. Regards

  • HABIB August 12, 2016, 9:55 am

    Dear My Generator Team,
    My 3 kva generator which is causing problem since a few days. It start normally, but does not generate power. First time it start generator power after two tries without doing anything. But after a week no more power generation. It stared working after cleaning the brushes & rings . Next time even cleaning does not work unless I flashed the generator with 12 volts battery.

    Now its not generating power even with the flashing. After changing The brushes it worked but only for 3 days. Then again worked with the flash.

    My question is that why its happening again & again?
    Is there any permanent solution?
    Should I changed to AVR also?

    • Lachlan August 14, 2016, 11:32 pm

      Hi Habib, its hard to say without knowing the type of generator/alternator etc. you have. Typically if a generator starts and the engine is running but it is not producing power, there is a problem with the alternator, or even issues with the outlets. You should also check that you have not tripped the circuit breaker by overloading it…In any case, I would suggest you take it to a local generator service agent for inspection if the problem continues.

      • Mitch October 30, 2016, 3:05 pm

        Make sure that when you turn it off; that you have nothing plugged in or even turn off the breaker before shutting the generator off.

  • Adam Jackson August 22, 2016, 1:17 am

    I have a 3.5kva gentrax that looks to have blown caps on the AVR. Does anyone know where i can buy a new board or even a wiring diagram to figure out which parts are blown? cheers, Adam

    • Lachlan August 22, 2016, 1:20 am

      Hi Adam, the distributors of Gentrax Generators are a company called Outbax Camping: https://outbaxcamping.com.au/
      I would suggest contacting them in the first instance for spare parts or technical diagram info. Cheers.

  • Lyell Haw September 9, 2016, 11:14 pm

  • TONY RYAN September 12, 2016, 12:41 am

    Hi. I have a Power Max – Tiger Model IN2500i Inverter Generator which has not done more than 10 hours running. It has been idle for a couple of years and was operating when last used. I started it to use it and it started easily and the auto-throttle works fine, however it has no output, either AC or DC, and after about 20-30 seconds of running the “Overload” annunciator lights up. My manual does not mention any fuses and there is no “Reset” switch or button visible or mentioned in the manual. Do you have any advice please?

    • L Adams September 12, 2016, 1:38 am

      Hi Tony, generally if the generator is running but producing no power, then it may have been overloaded (power draw from the appliance(s) greater than what the generator can produce) and therefore the circuit breaker has been tripped (which can easily be re-set for most models)…or your inverter board may be damaged, in which case you will need to take it to a service agent to be inspected; check your manufacturer’s warranty card for details. Cheers.

  • felicia September 21, 2016, 11:57 am

    Hi my generator pull cord is hard to pull. When I take spark plug out it is easy to pull. When I put it back in, it gets hard to pull again?

  • Neil Cadman September 27, 2016, 2:01 am

    I have a GenTrax 1.2kVA and the pull start is jammed . Sometimes it will pull a small amount but mostly not at all. Can I get the required part anywhere and can I fix it myself? Alternatively where in Brisbane can I get it fixed?

    • L Adams October 9, 2016, 10:19 pm

      Hi Neil, for the Gentrax brand, you can contact a company called Outbax Camping, who import these generators from China: https://outbaxcamping.com.au/
      Unfortunately this is a brand that does not have national accredited service agent or spare parts support. You will need to go through the distributor (Outbax Camping) to see if they can provide you a spare part or have the unit sent to them for repair.

  • Phil October 3, 2016, 4:52 am

    I’ve been using a Ryobi RIG2000, but now won’t start as no spark. The overload light comes on (NOTHING CONNECTED!) if turned over fast enough eg with sparkplug out. Manual says the overload auto resets after load removal (even though it was working prior to being stored for a few months). Still under warranty I think, but anything I can do re this? Oil is all OK.

    • L Adams October 10, 2016, 12:42 am

      Hi Phil – if you have fresh fuel and plenty of oil and it won’t start, then you may need to take it back to Bunnings (the exclusive retailer for Ryobi). Ryobi dont have national accredited service agents like Honda or Yamaha, so you may have to take it back to Bunnings and see if they will repair or replace under warranty.

  • Nick Buckley October 17, 2016, 8:51 pm

    Hi, We have an Aldi 3kw petrol generator (yes I know!) but it has worked perfectly on site and has run a fairly beefy drop saw without difficulty…..until now when it trips out using the same piece of equipment, whilst operating fine on lesser loads. To my ears it seems to be not running as strongly as previously.

    thanks
    NIck

    • L Adams October 17, 2016, 10:28 pm

      Hi Nick, tough for us to advise as we don’t sell the Aldi units…those cheaper Chinese models are often difficult to diagnose and finding a service agent willing to inspect and work on it may not be easy either…Hopefully someone on this forum can shed some light? Cheers

    And i’m trying to run a small pressure washer Nilfisk C120 6-6 PCA X-Tra with a 1400W motor.. but it doesn’t work correctly.. the Generator isn’t tripping out but the washer has little to no power and the motor spins once every 10/12seconds.

    Any advice would be great! the genny is brand new so is the washer.

    Cheers.

    Hi,
    My 2.5kw generator keeps sounding as if its on choke even when you remove it from choke. Kindly tell me what the issue may be?

    I just bought a 800 watt earthquake generator and I have 3 light bars on my boat. One runs 144 watts and the other two 125 range. They are rated for 10-30 dc and this is a 12 dc outlet. Everything starts up fine. I wait a minute to plug the lights in and they run 15-20 seconds and cut off. The dc circuit protector keeps shutting off. Every time I push the dc circuit protector they come on for the same as before and cut off. I don’t know what the problem is the rated load is 700 watts and this is not close to that. I don’t know what is wrong. If you have anything that can help me. Thanks Tyler.

    • L Adams January 13, 2017, 3:37 am

      Hi Tyler, we are not familiar with that make of generator but in our experience, using the DC outlet from inverter generators for prolonged periods is not always recommended. The DC charge is not regulated and it is designed only for a trickle charge for a short period (such as kicking over a flat car battery). I’m not sure if that is the cause of your issue, but it s worth keeping mind that your DC capability on your generator is not intended for sustained running of appliances. Thanks

      • Tony Ryan January 27, 2017, 3:39 am

        Tyler

        If your Generator DC circuit protection breaker trips it may indicate a problem with the circuitry of your light bars, such as a short circuit. Have you tried running some other low current draw appliance from the DC outlet to see how the DC protection reacts?

  • Simone January 26, 2017, 4:30 pm

    I have a customer who says they are pulling the cord on their inverter generator, but feeling no resistance and it won’t start? Any ideas as to why this might be?

    Thank you! Your site is great!

  • Tony Ryan January 27, 2017, 3:45 am

    Is your Inverter Generator actually being rotated when you pull the cord. Several possibilities. Could be the sprag clutch not engaging, could be (but unlikely) that the spark plug has become loose enough to allow sufficient leakage as to not start. I presume the starter cord retracts when released. A bit more info would be helpful.

  • Nico February 3, 2017, 8:47 pm

    Good Day I am lookin for a scamatic elecrical diagram for a Ryobi model rg-6900 engine starting side ,my dog got hold of the wires cumming out the bottom end of the control panel please help Regards Nico

    • L Adams February 5, 2017, 4:04 am

      Hi Nico, you could contact Bunnings about that type of information; they are the exclusive distributor of Ryobi generators in Australia. Thanks

  • Henry Norris February 10, 2017, 3:43 pm

    I have a Ryobi RYI 2000T generator/inverter. It starts and runs great, but the fuel tank had a leak so I took the unit apart and fixed the leak. Upon reassembly I found a part that I hadn’t noticed while disassembling. I believe it is the “Bridge Rectifier” from the drawings I’ve seen. I don’t know where it goes or how it mounts. It has what appears to be a mounting flange with a hole on one end. Any help would be greatly appreciated. This is the only thing keeping me from buttoning this up. Thanks.

  • kingsley February 12, 2017, 8:05 pm

    hi, pls help me out here, I tried servicing my generator cause there was no compression, I cleaned the valves and installed everything. The generator starts but over fires like crazy, I put it off immediately and tried starting it again, same issue, I’ve completely run out of ideas as the tunning screws doesn’t seem to work. I really need assistance from the house, thank you all in advance.

  • Peter February 13, 2017, 10:52 am

    Hi my Bushpower generator g1000i starts no problem but goes from green light to overload within 10 seconds and outputs no power.

    • L Adams February 14, 2017, 2:44 am

      Hi Peter, sounds like it could be an inverter or circuit breaker issue. I would recommend you contact Matson Australia – they are the national distributors for Bush Power – here is their site: http://www.tridon.com.au/products/Matson/
      Many thanks

  • Brenton Altus February 14, 2017, 9:05 am

    G’day. I’ve got a Honda APH33RS1 3.3kVA. Is there any way to get new parts? A fair bit of the plastic parts are broken as well as the single phase sockets.

    • L Adams February 14, 2017, 10:21 pm

      Hi Brenton, that model is an Advanced Power Generator – the parent company and manufacturer of the Advanced Power brand is M Power, who have spare parts. Their website is: https://www.mpower.com.au/
      Many thanks

  • kevin horne February 14, 2017, 6:14 pm

    What would cause a generator to start in weather 40 degrees Fahrenheit or warmer but not in 39 degrees or under? This is a small portable generator MCI 2500 (watts).

  • Brenton Altus February 15, 2017, 2:02 am

    Sorry L Adams, a search in mpower.com.au came up with nothing. Any other ideas?

    • L Adams February 15, 2017, 5:05 am

      Did you call them? Their number is 1300 733 004 – they have a portable generator dept. Thanks

  • Tony February 18, 2017, 10:10 am

    Hi,
    My generator runs but but as soon as I plug something in the generator kicks down to really low revs it produces power but a low power how can I fix this?

  • Alfred March 6, 2017, 9:17 am

    Hi Admin,

    My gasoline generator suddenly dropped voltage to 100v. The correct voltage is always 220v. Upon switching off and trying to restart, it completely failed. Kindly advise on the possible solutions of the issue.
    Thanks in advance

  • Gary C March 21, 2017, 5:20 pm

    I have a Sportsman 3000 that when I start it, it will output voltage for about 10 – 20 then even while its stays running it will stop outputting a/c voltage and I made sure it did not trip the overloads.
    Any ideas on what could be wrong?

  • Wozzer March 21, 2017, 7:49 pm

  • Simon April 14, 2017, 5:29 pm

    Hi, I bought a Grip 7.5 KVA Petrol Generator for my 2 room flat, when the power is out i use it to run my fridge, dstv, tv and 2 x 220 to 18 watt fluorescent tubes. I just tried to start it after about 6 months, using the battery and wont start so i started it manually. It is running but I am not getting any power from it. The V.F.T. METER goes on and of on and off. It worked in November with no problem. Why now all of a sudden? I got it cheap about 2 years and only used it about 5 or 6 times for about 4 hours at the longest. What could cause to suddenly not give power properly?

    • L Adams April 18, 2017, 12:57 am

      Hi Simon, it sounds like you have either tripped the overload breaker (by drawing too much power) which can be reset, or the alternator is damaged. If its the former, revert to the product manual to reset the breaker. If its the latter, this would require inspection from a qualified service technician. Thank you

  • Jim April 15, 2017, 2:10 pm

    I have a Ryobi 2000 Generator and the switch has three settings – off/stop, start, run. According to the manual the start position also engages choke. Should start with a couple of pulls, let engine warm up, then move to run position. I have two problems. 1. It will NOT start cold without removing the spark plug and putting some gas in the cylinder. 2. When it does start and warms up I can not move to the run position. As soon as I move the switch just slightly off the start setting it is like shutting it off – starts to die IMMEDIATELY. I can leave it on the start setting and it runs fine and generates 110 fine. Evidently the start setting is NOT engaging the choke thus the need to put gas in cylinder. Iam 74 years old and have worked on cars, engines all my life so not a novice with these things. Any suggestions?? Thanks, Jim

  • Tony Hayes April 26, 2017, 5:27 am

    Full Boar FBT 3100
    I need to remove the main cover on the carby side, but there is one bolt of some sort still holding it the cover together. Doesn’t look like allen key or screwdriver bolt or normal hex head, just a round bolt head with a round centre to it.
    It’s the one on the battery end, just below the fuel tank cap. Can’t for the life of me work out the sort of nut/bolt/screw to undo it. Has anyone got answers/suggestions please ?
    Regards
    Tony Hayes

  • Bill May 4, 2017, 10:21 pm

    Working on a powerhouse 3100 inverter generator as soon as i plug anything into it it gives me an overload fault puts out good voltage with no load also if i put it in economy mode it will give overload with no liad applied. Is the inverter bad?

  • LieEl May 9, 2017, 11:22 am

    My generator stayed in the garage for a year now, stored it with no petrol, think the timing is a bit out; if I try and start it gives a backlash. If you pull the starter coil it actually pulls the rope back and whips a person. Please help, just want to know how to set the timing?

  • mihael May 14, 2017, 3:19 pm

    hi, i ve got Clarke inverter IG1000. the inverter unit does not working-there is no 220 AC. the new one is very expensive, so does the board may be repaired, or have to be replaced.thanks

  • CHRIS0817 May 28, 2017, 7:46 am

    My RYOBI 2000Watts Digital Inverter Generator is rated to run 4.5 hrs. But why does it only run for 2.5 hours? how to get it back to 4.5hrs..?
    I hope you can help us…

    thanks…

    • L Adams May 28, 2017, 10:26 pm

      Hi Chris, my first though is that the ratings are load dependent. I.e. most generator manufacturers will state the approximate run time base on either a 25%, 50% or 75% power load. So obviously depending on the power you are drawing from the generator will influence the run time you get. Thank you.

  • graham June 10, 2017, 11:52 pm

    Hi, I live in Brisbane and i’ve recently purchased a GT6000 150cc fuel injected generator and well i’ve thought it was a diesel engine and stupidly put diesel fuel in it. Is there someone I can call to drain all the fuel from the system and filters etc and flush it and get it going as its only a few months old. Any help would be appreciated.

  • Cara June 12, 2017, 4:00 am

    Hi I have a Pulsar generator 1200 watts. When I start it, it doesn’t sound normal. It sounds more fast and louder. I checked the oil and it’s good, but there’s a hole in the cover of the air filter. I’m guessing it’s because of that.

  • Todd Sharron June 20, 2017, 3:41 pm

    Hello,
    I have a Tahoe 7000 diesel generator. It will start fine and run well until I switch on the power. It will run for about a minute then kill the generator. Any suggestion? I have changed oil, plenty of clean fuel…..
    Thanks
    Todd

  • Neil Streatfield July 2, 2017, 2:11 pm

    Hi,
    I’ve recently “serviced” the carby on my china 4.4kva(lol) generator. Now I’ve connected everything back up it won’t run. I’m pretty sure it’s a fuel issue (not sure I’ve reconnected everything correctly) . Would you have a photo/picture on how everything is connected, it would really be helpful.
    Cheers

  • MICHAEL POOLE July 12, 2017, 11:56 am

    Hi Guy’s 12 months ago I purchased a Fuji Micro Inverter Generator its never been used and is still brand new. Today I tried to use for first time, new fuel and oil level good but will not start. I have tested ignition coil both primary side and secondary side resistance of coil is as manufactures spec’s. Checked for spark with inline spark plug tester and found there was no spark, even though the spark plug has never been used.Tried several new spark plugs same result.I removed covers for a visual inspection everything seems to be ok’a no loose wires ect; the only thing I find strange is that the ignition coil is mounted on plastic cover which covers the fly wheel I’am wondering how this can induce voltage into the coil as the plastic is an insulator.With multi meter connected to one side of coil and pull starting cord there is no induced voltage present any ideas as this generator has never been used.

  • Kel July 13, 2017, 9:02 am

    I have a Yamaha 2400 is its running very rough and only seems to be outputting 101volts when it should be 240 volts ac.

    • Paul Campbell July 17, 2017, 2:15 am

      Hi Kel,

      That is a tough one. The machine would really need to be assessed.

      Yamaha Generator Australia provide national support service for the EF2400iS. You cal call 1300 735 440 to find a local service agent to assess this generator.

      regards

    Have 2500 geny, that i hooked up to mid size fridge. Ran for 2.5 hrs then stopped,after using half tank of fuel. Let geny cool down for 1 hr, then restarted geny, ran for half an hour then stopped. This has now happened a second time.
    Can you help ? please

  • MikeM August 20, 2017, 4:48 pm

    Aldi Workforce 3500w inverter genny. Has no spark – tried another plug also – but gives a ‘spark’ indication between apark lead and earth on multimeter (not sure how much volts should be there when pulling over).
    Main coil two wires has continuity as does very small pickup coil – strange very smooth flywheel has no inset magnetics – just a raised trigger spot – which does not seem to be magnetic… or if so, is only very slightly. Checked OnOff switch – ok. Coil is mounted on top of engine and carby has an electrical connection with a number of wires – (looks like a little electric motor mounted above carby)
    Any ideas anybody – don’t want this beastie to beat me – nor fund someone elses retirement fund.

  • David August 28, 2017, 7:26 am

    Why does my Honda EU30is turn the spark plug black and won’t spark after about 15 hour of running. Not in shed, so plenty of air, in fact new air filter, choke in. Not on eco throttle, giving 2.7 kw when running.

  • Rob September 1, 2017, 8:20 am

    Hi, I’ve got a Gen Trax 3.5 KVA generator. I need to clean/change the air filter. I don’t have a schematic drawing of the unit. Where is the air filter & how do I get to it ? I don’t want to pull the whole unit down if hit can be helped.
