How To Fix A Portable Generator

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

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:

How to change the oil in your 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.

We've tested a range of Generator Engines to find out the best performers

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.

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.

Thank you for sharing this easy fix to portable generators! You mentioned that each generator is designed to handle a specific electrical load. Are there other risks that could happen if the required electrical load is exceeded?

My Generator Response
Hi there, Most of the generator we sell have inbuilt safety protections for this scenario. However, repeated overload of the generators maximum output can result in damage to the generator. Thanks for your question.

Hi, Ryobi 3400/4000 inverter generator back for an update. I let the generator sit in my unheated garage for 11 hours (overnight). Same problem would not start COLD. Pulled cord several times nothing. This time I decided to Spray some carb cleaner into the carb with choke in the open position it did start. Could it be some internal problems with the carb? too much or too little gas? I'm running out of ideas. 25 degrees today.

Hi. I have a Ryboi portable inverter generator 3400/4000 watt. Model # Ryi4022x. When cold (overnight cold) it takes 12 or more pulls to get it started. Once started, I can shut it off and it restarts right away. So my problem is when it's COLD. I removed the carburetor cleaned it manually, poked out all the holds, removed the main tube and cleaned, removed the black idle screw and cleaned both inside the carb and the black fuel inlet. Blew compressed air through out and then let it sit in an ultra sonic cleaner with heat in gun cleaner solvent(Slip 2000 great cleaner) for an hour, rinsed off the carb and dried. The carb is clean. Looking at the choke it seems to be closed correctly when in the start position. I changed the oil to full synthetic Mobil 1 0w/30w. Changed the spark plug and gaped to 0.26 the manual said between 24 and 28. I went in the middle. Emptied the fuel tank blew the inside dry and even had a small vacuum ( tank completely empty) and tried to suck up any dirt inside the tank. The tank is clean. Put in 93 octane with stable mixed into the gas. Checked all fuel lines. Fuel is making it all through the system to the carb. No leaks of fuel anywhere. Tried starting the unit cold with the oil pressure switch disconnected. (didn't Help). Cleaned and oiled (not to much oil) the air filter. Spark arrester is clear. I put in a new fuel filter. I am currently running the unit with a 500 watt load for one hour. I want it nice and hot to let all the new fuel, oil etc to work its way through. It's now 28 degrees outside. I will let it sit over night to see what happens when it's cold again but I've tried this before with no luck. The only change is the Mobile 1 0/30. I had Mobile 1 5w/30w. Maybe Valves need adjusting. Please share your thoughts. Thank You.

Hi there, When I run my generator in freezing temperatures (like -5 C) it often "swings" like jump from very powerful run to almost stalling and back every second or so. My guess is that the system that regulates fuel intake according to the connected load becomes sluggish / not responsive quickly enough. Maybe some parts of it freeze or something. Does that sound like a common issue? Would it perhaps help to lubricate the levers/springs in the load/fuel regulation mechanism to prevent them from losing agility when it's freezing? Thanks!

My Generator Response
Hi Eugene, We recommend seeing a small engine mechanic. The cold temperatures are probably causing the issue, but there could be something else at play. It sounds as though it could be engine / fuel related. Please let us know if we can assist you any further.

I have a Powerhouse 2700 inverter generator that has never been started and is about 4 years old. I put oil in, fresh gasoline and when I start it, it goes to full throttle and overload light is on with nothing plugged into it. I moved the throttle plate(manually) and it stayed at mid throttle but overload light was still on. Turning the “ECO” switch on and off has no effect. Thanks

My Generator Response
Hi Jesse, thanks for your question. From what you've stated it sounds like a fuel issue. Being a USA generator that we don't deal with, we would have to recommend you contact your local service agent. Sounds like the carburetor or jets are blocked. Leaving fuel sit for that long will definitely have adverse affects to the engine. You can check out our blog on Generator Maintenance and Safety Tips for more information.

Hello i also have a problem with my impax (im8001) my fuel finish ,i put another fuel and that is how the problem started if i starts the engine and set the choke to choke position the engine work, but when reverse the choke to run positon then the engine dies , and it get very hot ,i dont know where the problem is i need help thank you

My Generator Response
Hi Shatu, I am not sure the exact model, so you should always contact your local repair agent for that particualr Generator. I can advise on what it could be. 1) If it is getting very hot, there may not be enough oil, or the oil may need to be changed. 2) The air filter may be blocked and need cleaning or replacing as air is not getting in to cool the engine. 3) The carburettor or jets may need to be cleaned or replaced as fuel is only getting through on full choke regards Paul

I have champion 3000 generator that runs fine but can’t power anything more than a small space heater. I plugged it into an RV and it sounds like the engine really has to work and keeps cutting the power off and on. The RV’s power box really whines whenever it’s getting power. Also the generators volt gauge shows 120 volts fine even when it’s feeding power to the RV. I hooked up my uncles older 3000 champion and it ran the RV perfectly with ease and the power box in there was quiet so it’s not the RV. Any ideas?

Hi, i have a Zipper 1200iv inverter Generator and my question is if there is an option to throttle up the engine like the Eco switch on a honda inverter? The inverter circuit of the generator shows several unconnected pins and i assume that two of those pins connected could result in a throttle up. My Problem is if i wanna charge some Lipo batteries on the field (the Charger draws about 800W), the Charger shut itself down because the voltage drops so hard as i start the charging process. And sorry for my bad english, I'm not a native English speaker.

I have an 1100w generator but will not run a 650w hoover (HENRY)

My Generator Response
Hi Doug, I'd suggest that your Hoover draws more power upon starting up and so your generator is not coping with that initial max power draw. Many appliances will have a start up power requirement in the order of 3-5 times the running power. Therefore you may require a larger generator. Many thanks

Dear MyGenerator team, I have Suzuki 2.4 KVA generator. It was working very well. From last week when we put 600 to 800 watts load ,it lose its power and voltmeter shows zero. when we reduce the load it becomes fine. We have to use this generator for the power for which it is designed for that is 2.4 KVA . At least it should give us power of 2000 watts which it had been producing previously. What is the cause and what will be the solution????

I got a 2 cycle 1000W generator yesterday, brand new. Got it to charge a teardrop camper battery and run small Watt devices (nothing over 500W). In the process of getting it setup and connecting devices, the circuit breaker tripped a couple times. Now, the generator puts out some power (75 volts) but not enough to run things at full capacity. Doesn't respond to loads now either. Any thoughts on what it could be?

Hi, I have a generator and yesterday it ran out of gas and I refilled it straightaway. The thing is, I waited for it to cool down overnight and it won't start this morning

My Generator Response
Hi Cristal, Any good portable generator should come with a comprehensive user manual with a section for trouble-shooting. If the generator has a choke, you may have to start with the choke on. It is always a good idea to check the spark plug is clean and intact. You may want to contact the local service agent in your area for further diagnosis. regards Paul

Hi, I have a Clarke IG1000 1kw inverter generator. I tried to use it to run some lights etc at a party and after about 10 mins of running it showed overload and cut the power (engine carried on running). There wasn't a lot of power being used, and we had another generator (1.2kw) running the audio equipment. After resetting it would work for about 10 mins again then trip every time. In the end we ran all the audio equipment and lights on the second generator which worked fine, so not an issue with the lights. Any idea what the problem could be? Thanks.

Hi I have a wolf 2300 generator runs fine but as soon as I put any load on it cuts out Any ideas how I can fix it Thank you Daz

My Generator Response
Hi Daz, That sounds like the inverter or the alternator has gone. It may have been overloaded at some point. You might get lucky and only have to replace the capacitor (if it is that type), but most likely it will be the inverter or alternator that needs replacing. To know for sure, you should take it to your local service agent for diagnosis. At My Generator, we ensure that all of our products come with a service agent support around Australia.

Hello I have a question as to what would make a generator power things then it won't power but is still running. There's no problem starting or keeping it started. After its start it will power something then just stops. There's a indicator light on it and when it's powering fine of coarse it's on then when it stops powering that light goes off. It does staying running even though it won't power anything

I opened my new Fuji Micro F4200i , fueled, oiled, would not start. Followed the manuals checks and when I removed the plug using the supplied spanner, disaster - as the spanner does not actually grip the plug, once it is undone fingers are needed to get it out. A diificult area, plug disappeared in to the cowling area Note: use a proper plug socket that keeps a grip of the plug!!! anyway, I had to completely open the genny up to get at - jammed in between two fins and broke a couple as I had gently pulled the cord to see if it was caught up, IDIOT - it was. I normally take a phone shot of any wirinf connections but as all bar 2 were plug 'n play connectors I didn't. Mistake: I now have a shortish black cable from the black cylinder from whence the plug cable emerges ( other cables going in. I have found only one place where it can reach and attach but not too sure -one of the bolts that holds the plastic casing over the recoil start & alternator, so it would be earthing to the engine> As it has marks on one side i assume it is meant to be connected somewhere, but the again it may only be used for the electric start version. I have a photo if it makes it easier

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.

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.

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...

My Generator Response
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.

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

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?

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

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?

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

My Generator Response
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

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.

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.

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.

My Generator Response
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

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

My Generator Response
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

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.

My Generator Response
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.

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?

My Generator Response
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.

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?

My Generator Response
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.

I would like to get a copy of the wiring cct for a G1000i inverter generator (Unit has overload light up perm.)

My Generator Response
Hi Lyell, we don't sell the G1000i model. It is not a model from a premium or trusted brand. It looks like it might be from the likes of Bush Power (http://www.tridon.com.au/products/Matson) or a brand called Sealy (http://www.sealey.co.uk/). I would recommend contacting them for any diagrams for your generator. Thanks.

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?

My Generator Response
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.

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

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

My Generator Response
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

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

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?

My Generator Response
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

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

My Generator Response
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.

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

My Generator Response
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.

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

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

My Generator Response
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 :)

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?

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.

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?

My Generator Response
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.

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

My Generator Response
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

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 Response
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.
