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

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).

I am a 57 year old woman living alone, I just want to say thank you for this video. I have never done this type of thing before, but everything you said worked and I fixed my generator! Thank you!!!

My biggest problem with repairing generators is the skill checks and the murderous person trying to kill me while I am fixing the generator. This video is a huge help.

Retired now what? Well picked up a lawn mower repair addiction.,but to much rust and too little profit.Then i got my 1st pressure washer.To heck with lawn mowers they dont squirt squirrels in trees.Im getting pretty good .Fixed 50 this year doubled my investment and love them varmints.Now generators thank you ist one fixed today.I love fixing what'dý others cant. Thank you.

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😁😁😁😁😁😁

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

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.

Thank you so much man, I literally have the same generator and was confused when I didn't see a AVR on the bottom but your video help a lot thanks

Thanks for the tip about not letting the gas run out. Makes a lot of sense. David

Thank you. So easy fix. Worked like a charm.

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 👍.

Great job!! Glad you were able to fix it on your own. I find it very satisfying to repair my own equipment and especially NOT having to purchase another of whatever it may be if at all possible....lol.

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.

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.

WE CAN'T HEAR YOU and you showed us the old AVR upside down for the numbers friend, but got it right with the new one. You did it!!! Thanks for that. I enjoy these generator repair vids, so a thumbs up.. !

Great video. Found the melted AVR in my 2005 Prosource 6800w generator . Ordered new item thru e-bay as noted-works great. 6/13/2020.

wrong name but right course of action....now it inspires me to check my capacitor too...

Great info and easy to understand. Thanks for sharing.

Had the same issue poss 8years ago . Replaced the capacitor for $50-.. And works like charm

Nice job of troubleshooting and repair!

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.

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!

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.

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.

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

Great video. Glad that you were able to fix her up!! Nice job!

I’m glad I come across this video! I’ve got the same generator that runs bur does not put out any voltage ! Thanks

Nice video, thank you. Probably demanded too much current that's why AVR blew.

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.

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.

had an older one given to me, first I changed the breakers, at least one was bad anyway, then I got it going with the drill trick.

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.

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!

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.

Great video man. Thanks so much

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.....

Good job. These capacitors are so inexpensive, I like to keep an extra on hand....

Just noticed this video is three years old. LOL Hope I wasn't too late with my comment and the generator is still working.

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...

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

I'm digging this music between work!

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.

Great work! Thanks for sharing! Just picked up a Yamaha EF2600 for a song, runs great, no power, gonna dig into it tomorrow. 😁 Never worked on a generator before, but I'm no stranger to mechanical work, should be interesting!

Sally Safety here...I sure hope that those are OSHA approved sandals that you are wearing ! Nice repair BTW .

Alright thanks for the help now i can open the exit gate and probably escape the entity’s realm

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

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.

You can get these _a.c. metallized film capacitors_ out of *old ceiling fans-* just *parallel the values* to get the value you need. That way you don't have to wait for the cap to arrive on a slow boat from China- and you can have your generator up and running in minutes.

Awesome I will try this on my generator. Thanks for sharing

Hope this will help me through my studies

You made it man! Thanks for sharing!

This guy would survive Dead By Daylight

GREAT JOB, BRO!

Thank you so much for making this video, I have the same exact problem and have tried re-magnetizing the motor with no luck. I'm going to go open up the panel and check the avr right now. Thank you, thank you, thank you.

I have one. and do the same thing thanks for the video I fix 2morrw 👍👍👍👍

ALWAYS TURN OFF ALL ELECTRICAL APPLIANCES BEFORE STOPPING OR STARTING GENNY... GOOD PRACTICE.

Dorian on his way and got out the generator . Runs great , panel meter shows output but no power from the outlets , thoughts ?

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

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.

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.

What is the black square down around the 4 and 5 o'clock position? It looks like it could be a rectifier and brushes assembly.

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.

Some gens have an AVR that looks like a half-moon with or with out ribs, silver or black. and for the most part have 6 wires leaving them. 4 together that go to a plug or maybe just connectors and two other wires maybe red an white go to the brush set and it most likely has a + near spade lug. Other gens like Troybilt and a 5KW power+ have a brush holder, actually has 2 brushes and a rectifier bridge on the back of it. two wires from st8r go to this fullwave rectifier to change slight amount of a.c. to d.c. making rotor to have a lot more magnetic field to it and in return, you get ur 120/240 volts. I never had any luck with the drill job but if the rotor has slip rings I juice'em with a battery, careful to mind polarity. if gen is a brushless there is a capacitor in st8r circuit, it could be bad. they don't last forever, but mind it could be good and u could get a zazzz . those button type breakers could go and if one is for the 240 volts u will not get it but half instead.

Rite on thnx man big help👍👍

I tried the reverse method and it worked for me, thank you!!!

Awesome!

I have the same generator but 2500 single pole 110vlts. It’s kicks start but doesn’t produce power voltage. I know exact what to target. Thanks for the video man!!!

Great work!!

Good job man !

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.

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

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.

Nice video mate thanks

Well done.

Good fix

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

Great video you have given me a lot of tips of what to look for thanks .Question my generator is still producing power to charge batteries just no 110 was yours doing the same could you let me know it would be appreciated Thanks very much Dale

Hi there! Hands on channel, actually u r part right. U need a bit of magnetic field or residual field just like in old car GENERTATORS, not ALTERNATORS. if ur gen has slip rings it has d.c. voltage applied to them. can't see what u r talking about but it sounds like the battle of the BULGE. yeah avr's or caps when overheated get messy. hope the new 1 works, most likely it will. keep up w the engine maint. too! clean air filter when u change oil as a dirty one will make engine run a bit rich. as the ratio of air to gas changes.

Good video, had the same problem

Capacitor. Look at the microfarads. Look up an aftermarket that meets the stats and save money.

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

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.

Good work 👍👍👍👍👍👌

Worn brushes can stress the voltage regulator. Good idea to check/replace those at the same time. I also solder all my connectors/lugs so they keep a good connection. Sometimes the crimps are poor or corrode. A little dielectric grease on the push-on connectors keeps things nice.

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 .

The drill trick does work ive done it it’s called flashlight the field I replaced a bad rotor and had to do it .

Awesome man thank you

Thanks for posting!!

Just bought a new Wen 4050, I was looking at the wiring diagram and couldn't figure out what AVR meant, now I know, DUH.

Thank you!.

Nice job.

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.

Very cool

Good info, thanks !

you may have to flash the field coil.

Good diagnostics - what song is it you play during the video? I see some didn't like it but I did. thanks.

I have this same prob except mine busted through.. Exact same model. Could you provide me with a link to where you found the part?

Cool thanks 😊

Since it is a single phase gen, you have two hotlines and a neutral. If the neutral is bonded then u'd want to use 3 wire extension cords. otherwise if u have a fault, u can get a pretty good zap. just cause electricity will go to ground it still wants to go back to the source and if the legs of the frame are on the ground with no rubber, using a 2 wire cord and a faulty item w a neutral bonded to frame, gen. yes that can be dangerous.
