Generator Repair - Troubleshooting - Runs But No Power

My UST 5500 watt generator stopped generating electricity the last time I was off grid. In this video I show you how I fixed it. Thanks for watching. Be sure to check out our other shop related videos.

I tried a grinder and hooked my drill to it so I could turn it in reverse easier and it worked!! I’m blown away crazy that it worked

[@brianstewart3457]

Hi, Well done you fixed it. In your case it is just a capacitor (24microfarad 400VAC) and you are correct, it is OK to fit a higher working voltage part so 450VAC is OK. The part is not polarity sensitive, so you could have wired it either way but it's good practice to retain polarity if in doubt. In your case it's a capacitor (2 terminals) not and AVR. An AVR (Automatic Voltage Regulator) contains a number of electronic components and usually has at least 6 terminals (4 for exciter winding and voltage sense and 2 for the rotor brushes).

[@fuegoalmaximo1666]

I did it .plug a grinder in outlet with generator on then started to pass it backward on a plywood panel . holding button on grinder and in 10 seconds it turn on. I praise the Lord.and thank you for the video God bless you and your family😁😁😁😁😁😁

Thanks for the troubleshooting tips. That cap was definitely overheating a bit. During Irma I ran one generator for about 4 days and then it quit producing, fortunately, I had a spare that was available and just rolled it into position and fired it up. I have not had time since to troubleshoot the Generac 5500, but now that I have some ideas, I guess I will get the tool kit and get busy on it.

[@Freight_Train]

You inspired me man. I overloaded my generator and it stopped producing electricity. I took off the panel of my generator like you did but did not have a capacitor or breaker that was bad. Kept following the wiring to the housing for the copper coils (the actual generator?) and found the capacitor that was melted. Ordered a replacement for $16. Bing! Thanks for sharing your video. Saved me the cost of a new generator.

[@43mackmobile]

There is a capacitor on the AVR also and it will over heat also.

Thanks so much,I saw your video and I tried everything you said,and I saw the problem on yours and out nowhere I just order the same element that was swollen on yours regardless mine was not swollen at all,once I received the part I went ahead to install it,and ir worked just fine,thank you very much

[@alanlind5078]

Appreciate the video, got my generator back online with your help

[@darrylfrizbee7134]

I'll be damned. Hooked up my corded drill into the outlet with a Phillips bit in it and barely clamped the chuck of my cordless drill onto the Phillip's to spin the corded drill. Had my multimeter plugged into the out and and spinning the corded drill produced 10 volts and after about 30 sec of that my corded drill started running off the generators power.

[@TheHandsOnChannel]

Nice!

[@jasonwb6884]

That sir is a capacitor. 24 microfarad.(mfd). Capacitor is used on ac motors or generator. Excites stator coil. All A/C single components need them. D/C motors or 3 phase motors don't need them. All capacitors work the same, just need the same capacitance value +/- 5%. never use a replacement capacitor with lower voltage value. You did great job finding and fixing issue. You probably did nothing to blow capacitor, They get weak, leak, and blow up. Almost all capacitors today are junk. Old ones used a oil that can't be used on capacitors today.

[@barreraruben]

Jason WB my generator is a 7000 watt Troy bolt and it shuts off when I turn all the power on my food trailer

[@SynKronos]

Not quite. AC brushed caps impede arcing by smoothing so that the commutator and brushes don’t fry. Where as in brushless like here are used to generate the initial magnetic field. Typically when a generator is over revved it causes the breakdown in the cap. Running out of fuel under load in this case is definitely the cause of such revving and subsequent fault. *Edit. One can put a higher rated cap on and equally install two in parallel. In this instance though if one is to over rev two would best in series which splits the voltage in half on each. This can also be helpful if you have a faulty governor in which case you would keep blowing caps.

[@SynKronos]

barreraruben Do you know how much current your trailer draws?

[@justinhall1844]

Good comment. I'm not critisizing but i dont believe all single phase motors require a capacitor. A shaded pole motor like a bathroom exhaust fan for instance.

[@Safetyworx]

Great information. Thanks

[@aaronanthonymoat]

Thanks for the vid, just got two gens from the dump, one had brushes gone, the other I think is the avr. Not as big as yours but beggers can't be choosers, lol. If anyone finds one from the dump, make sure that It's not an inverter one and there is no smell from the alternator.

[@TheHandsOnChannel]

Nice score, good luck.

[@KennerIAm]

[@aaronanthonymoat]

@@KennerIAm Because its really hard to find what's wrong. Some of the parts are cast in resins and can smell and look OK but are not. I got two and still can't figure what's wrong, lol

[@rubbnsmoke]

It might be a good idea to get an extra AVR to keep with the generator for an emergency fix IF you're off grid working and it goes out again. For the $24 it would be worth it if you had to replace it again.

[@TheHandsOnChannel]

I agree and spare glass fuses. Thanks for commenting.

The next hunting season he calls me up and said it won’t start . Well I figured what was wrong before I got there . The fuel shut off was shut . Duh

[@chuckpippin8415]

I have found over the years if a generator has set for a while, flashing the field will excite the circuits into producing full voltage. The best way I've found is to start the jenny, plug in an electric tool with the switch turned on...then plug a test cord into one of the outlets and just BRIEFLY touch the two leads of the test cord to a 12 VOLT BATTERY...just stroke the terminal and instant 120 volts. You may have to adjust the speed governor up or down to tune the output voltage as it is determined by the rpm. This trick will usually work if not being used over a period of time is the problem...gennys like to stay busy. Good luck.

[@DavidTheCarpenter]

Is it the amperage that counts?

[@2_be_determined]

This is good advice sir thanks you.

[@MyNeowolf]

rpm's control the cycle frequency 60hertz here or 60 flipflops per second. regulator controls voltage hence the term "voltage regulator"

[@Billydevito]

Cheap generators use capacitors as regulators. Better generators use proper AVRs. The capacitors tend to fail after a while. Higher voltage ratings means better insulation properties. Stay with same or higher rating. The ‘u F’ is the Micro-farad rating of the capacitor. Best to stick with the same rating or as close as possible. Good vid. I give you a 👍.

[@davidbivens2246]

That there is what you call a capacitor.. if you are not getting power I would guess it to be a run capacitor, and not a start capacitor.

[@gott2641]

I found a small Coleman Powermate 1500 in the garbage this past week, which needed quite a bit of work just to get running. When I finally did, I too found that there was no power to the outlets. I remember seeing this similar black box that had a broken tab, and wondered what it was. Now that I know, I'll try going back and see if that is the culprit. Would be nice to have a smaller generator without spending the money on a new one!

[@johncantrell614]

Yup, a general rule is never shut a generator off under load. Always turn off the breaker, or pull out the cord to whatever you are powering before turning off the generator.....

[@user-ut9ln4vd5m]

They should design the generators to automatically stop generating power if the RPMs / Hz drops too low... but then they might not sell as many new generators... hmm

[@sgtcote1]

Thanks for posting. I'll be checking which AVR I have on my Gennie and have it on standby. Cheap and easy fix when you have no power to order a replacement.

[@charlesroberts3910]

@@sgtcote1 yeah order early sometimes parts become obsolete

[@MsDave64]

Your Generator engine sounds fast, it may be running more than 3600 RPM which would change the frequency to over 60 - 62 HZ. That could be what fried that capacitor it uses to regulate the voltage. You might want to check the RPMs and reset them if that is the case. It may save you from having the same problem again. Your Multi Meter should have a frequency setting on it. Check at one of the 110 plugs.

You're welcome, thanks for commenting.

[@SteveHacker]

24 microfarad capacitor. Capacitors are electronics components that pass AC and block DC current flow. They store charge, smooth and filter power, and yes, even out of circuit, they can store enough charge to hurt you. If this had been a large electrolytic capacitor out of a vacuum tube television, tube radio or audio equipment, you might have found yourself picking yourself up off the ground (if you were lucky)... Good (and lucky) job! For future reference, always know what you are touching before you touch it...

[@TheHandsOnChannel]

Thanks, you are correct about capacitors being potentially dangerous. I normally discharge any cap I work on but since this one was melted I wasn't worried about it. My confusion was weather it was an avr or a capacitor. This is a brush-less motor and Ive read they use avr not a cap. The new part said gen cap avr @9:24. I guess it really doesn't matter what they call it, it works now and I didn't get electrocuted. WIN WIN.

[@raymondgarafano8604]

I read where Ben Franklin got across a battery of leyden jars, (antique capacitors) sed it was about as bad as sticking a red hot branding iron into a keg of gun powder.

Awesome video man! I have one just like this and I bet mine has the same problem. Big thanks!

[@austinlawler1827]

I'm digging this music between work!

[@SynKronos]

It’s a cap and given its AC it’s not polarised so doesn’t matter which wire goes where hence both wires being the same colour. Most are cans so you are very lucky to find a melted plastic casing. In future, check fuses then cap before anything else. *Edit If it keeps blowing you might want to either up rate the cap or put another cap in series. This will split the voltage over the two so minimising internal arcing which gives rise to the failure as the dialectic material breaks down.

[@rodolfoplasencia4953]

Thank you SynKronos, I was able to see is a Capacitor of 24 micro Farads. But I didn't know the following explanation you gave us!

[@rodolfoplasencia4953]

Uprating will means to go higher on the micros like a 30 mf? How could you connect a cap in series? I work in the air conditioning a/c field. Many equipments use capacitors. We use them connected having a cable from lets say a condenser unit contactor leg to a common connection (C) written in Caps of three connections. Then we connect a cable from the compressor to the connection H for hermetic, and the cable for the fan to the F marked connector, that way the capacitor gets charge from the contactor, kicks it up to the compressor and fan and both start. But this in series connecting a capacitor I don't know. For those with more questions about a/c you can reach me at 7864396047. If I know the answer to your question I'll give it to you. Mr. SynKronos if you can illustrate us more, please do so. Thank you!

[@MrFergeson]

I am currently working on the exact same generator right now. My problem is it needs to be excited every single time with the drill to put out. There is no AVR, it has 2 diode sets internally mounted on the rotating windings, which help excite the main windings. I suspect one of the diodes are bad, which I think I can fix but have to remove the armature. They use this same setup on some locomotives only on a bigger scale. DO NOT--repeat- DO NOT rev up any generator to try to get output. The windings will let loose with tremendous force. As a side note, The unit will run fine even if both fuses are blown. They are for the 12 volt battery charge DC output circuit, and for the circuit that will power the fuel shutoff/solenoid valve when engine/generator switch is set to off. It powers the solenoid as long as it can from the generator until it stops turning/putting out. The ignition will shut off unless defective. But I believe the fuel shutoff solenoid is a safety function so all fuses must be good. When switched to off, this actually grounds out the ignition coil.

[@rodolfoplasencia4953]

It even cranked, ran and sounds way beautiful after replacing the 24 micro farads capacitor! You may want to have an extra just in case. $26 is worth to have an extra when you need it you'll have it right on your emergency replacing parts kit place. I just come up with that one. I try to have extra parts for all I can and sometimes I know I have them but where? I have to create this place in my cabinets so whenever I need something I better go there first lol.

[@GeneticsSAIF]

Not sure of you can help! I'm in CA, due to fire season Edison been shutting down power... Long story short, I got this a nice Costco generator (Firmam H07552 7500 WATT DUAL FUEL ELEC.) It powers the whole house (not the AC unit or washer/dryer) Btw, we got no gas, so all electronic! I have solar installed that is connected to the grid and requires 20A When powering up the generator thinking it will power up the solar system and results in powering the whole house with AC, the solar system gives Abd error that frequency is not steady. My question, how can I assure that the generator output frequency is steady ? I was thinking like an AC unit where it needs a capacitor, what would you recommend? Btw, I have the main grid breaker off in case power comes back and connecting the generator thru a 240V 50A RV outlet I have (back powering the panel) Thanks

[@TheHandsOnChannel]

Sorry, I'd have to be there for something like that (too many variables). I know generators typically put out a modified sign wave __--__--__--__ something like that. Square wave, I believe it's called. Your system may require a pure sign wave signal to operate normally. If you have a system with batteries you might be able to use the d/c side of the genny to charge them. Good luck out there man. Maybe someone else can chime in with some suggestions.

[@MrCelticatheart]

The part was definitely a capacitor that is used to flash the generator each time it is started. Microfarads and voltage are listed on the unit so any capacitor with the same values will work! I am guessing that you would not want to run a bleed off resistor between the two terminals however!

[@nickb1875]

If u check on those 5k and 5.5k gen sets, if they have fuel shut off solenoid, they are more likely to have some independent coil for running the solenoid and charging the battery. I normally use that 14v DC to self excite the gen set. U jst undo the lugs from the brushes and take note of the polarity then connect the charging output to the brushes in respect of polarity. Run it fo about 5 sec and stop it then reconnect that avr to brushes done.

I've got the ,8500 that i boight at a yardsale. I out a new carb on it and it fired right up, but it's not producing voltsge unless it's at full throttle.

[@danburch9989]

Capacitors aren't specific to any equipment. If the equipment needs a 24uf 400vac electrolytic capacitor, then any 24uf, 400vac electrolytic capacitor will work. A higher voltage will also work as long as it isn't too much higher. It's the physical size and mounting of the capacitor is the limiting factor. We call it Form (physical characteristics), Fit (can it be installed where needed) and Function (will if funciton as intended). Note: I editied this to further specify "electrolytic". A capacitor that's made for DC circuits can be substituted in this instance.

[@43mackmobile]

An electrolytic capacitor is used primarily on alternators and electric motors that are brushless and they store line energy in the absence of brushes since the rotor or amateurs have no physical connections to the field windings and either excite or give a heavy amperage charge to the rotor or amateurs .

I am assuming when people refer to an electric energy that is dissipated the reference is to the capacitor which possible it looses the residual charge over long periods of time not being activated . That is why techs recommend running the generators monthly or bi-monthly to not only test the gas engine but the electric generator via the capacitor. At least this is my thought of explaining the issue. I m not a generator tech so I could be wrong.

Ok I took another crack at that small generator. What I did this time was give it a zap of 120VAC power and sure enough it came to life. I had a vacuum hooked up to it. I made this rig that consists of a light, a cord and two wires and if you touch the two wires together the light would light up. I touched the two wires to the capacitor when the generator was running and that sparked it to life. Killed the bulb though. The power is a little low about 90-100 volts any ideas why?

[@TheHandsOnChannel]

Not without seeing it myself, but try it again and flash the field coil. Sounds like you're making progress.

[@tarsneyisleestrelas4659]

@@TheHandsOnChannel the breakers when off show no power but do when switched on but will try the drill tomorrow.thanks for replying.

[@joselugo8866]

You made it man! Thanks for sharing!

[@w5monkey]

After you "flash" it check voltage, mine was at 160 volts and since the avr didn't have that little adjustment screw, I heard it may be the capacitor.. What a rabbit hole

[@anthonyforrester9437]

Field is the word he was looking for eh? P.S. My God! @some ppls comments huh? Wow. Good video brother...

[@mikepatterson3569]

I was just given an old homelite generator and I think the brushes are bad - problem is homelite doesn't make the originals anymore. Can I use others like you used a bigger cap?

[@TheHandsOnChannel]

Not sure but I'd try it. Brushes aren't that different I'd just look for some that mount the same way. Good luck.

[@chrisdevitto4340]

If it uses a large cap it is usually a brushless generator no avr. These can produce very dirty power so no sensitive electronics. To test these generators just set multi meter on ohms and probe through hot and neutral outlets with breaker on and gen off. Usually .4-.8 ohms that tells you the stator is good then go to cap and test on meter. Very rare to have a rotor die but it can happen.

[@bentboybbz]

But i like it when the charge gets sucked out of my unit.

[@TheHandsOnChannel]

LOL you sick freak!

[@Redawg58]

Maybe you should stick your unit into the 12V socket for a real charge.

[@gregorym9591]

You folks are too much LOL LOL LOL HA HA

[@jonathanbenoit8828]

Good work 👍👍👍👍👍👌

[@TheHandsOnChannel]

Thank you! Cheers!

[@MrRainbowrooster]

Liked your video EXCEPT the grinding heavy metal music. Never assume people like that noise. You just didn't need that.

[@Autistic-Uhbuddy]

Yeah Bubba, I know this video is old and you’ve already figured all this out but if I’m assuming correctly, you figured out, you had a brushless generator

[@dpatt45]

Have a similar generator 3500 watts that runs but no power. It was running and I was running a leaf blower. It started to slow down so I looked at the generator it was smoking. I shut it down but, on restart it had no voltage. Do you think this gizmo could cause this? How can I check that the generator windings are still good? Thanks in advance for your help .

[@TheHandsOnChannel]

First check the breaker switch. It should have a breaker reset switch. If that doesn't work check the capacitor/avr. (the part I changed out in this video. Good luck.

[@GamersDiary88]

I have a generator an its resistor is broken and the resistor is damaged i cannot find the resistor value to replace a new one .can you help me

[@williamhogg7830]

1/2 drill motor, put the drill in the FORWARD POSITION, hold the drill in one hand , and with the other hand turn the chuck in the reverse rotation .

[@BajaShine]

When replacing a generator, consider An Aurora diesel, very reasonable w/all copper wiring They're very quiet, reliable & efficient! w/remote starting capability.

[@cryptic_sans2637]

Here just incase I wake up in a entity consumed area having to repair 5 of these

[@TheHandsOnChannel]

It could happen!

[@jbodden6977]

YOU CAN RESTORE THE RESIDUAL FIELDS TO THE ROTOR WITH A FLASHLIGHT BATTERY. THE GENERATOR WILL RECYCLE THAT TINY CURRENT, ADDING ON TO IT EVERY CIRCUIT AND RESTORE THE FEILDS WITHOUT ANY PROBLEM.

[@TheLittlered1961]

Great video except for the music. Might want to tune the gen a little bit under full load. Get it between 115 and 120 volt. Should be running at about 3600 RPM. One more thing. Must calculate your total load. Do not run over 75% for long time periods.

[@Deucealive75]

I set my little 3.6KW to 120 volts at 50% load. 83% load it showed 118 volts. No load was 123. If you have to run 75% load for extended periods you need a bigger generator.

[@rherman9085]

They call that "Flashing the Field"

[@TheHandsOnChannel]

Thanks, I couldn't remember what it was called.

[@coondogtheman]

An update on the generator. My other generator has no capacitor in the control head where the plugs are. Question, can I get any 2 wire capacitor that has close to the same microfarads as the old one? I looked online on amazon and they have 12uf and 15uf caps and 250VAC rating. the small generator only has one 120vac outlet. Will one of these caps work?

[@TheHandsOnChannel]

I was told as long as the uf# matched up and the listed voltage was higher than the one you're replacing it will work. Good luck, I had a hell of a time finding the correct part for mine.

[@coondogtheman]

The Hands On Channel does the uf have to be exact or can it be one or two uf higher or lower. Found some on Amazon a 15uf one and a 12uf one at 250VAC. The generator I'm fixing is a small 1500w unit with 120vac only.

[@coondogtheman]

The Hands On Channel I am only able to buy off Amazon just fyi.

[@TheHandsOnChannel]

I don't know. I think you should call around to some local small engine repair shops. They might have the part or be able to tell you if a different uf could be used.

[@coondogtheman]

The Hands On Channel I'm going to do that. There are a few places in my area that might have one. I did find one exactly like the old one. 13uf 250VAC on Amazon but that will be last resort. Is this usually the issue? Because I get around 12 volts AC and I plugged a small chopper and it tried to turn. I guess that small voltage fills up that capacitor and then it starts the 120vac output.
