Great 👍

Great video. The best on here for this type of fault. I have ordered a new AVR. Thanks.

Do you support Kubota generator?

I have 110 on only 1 plug on my 220 output?

Excellent video...thanx! Is there a way to test just the AVR in order to see if it's working or not? (I am a novice at generator repair, and my 6.5KW 220v gen suddenly has no output power). Thanx & Regards, Alex Cape Town.

Enjoyed your video. Good step by step with really good info like why the gaskets go the way they do, how to make sure the governor lever and springs are right, importance of the OHV cover tube. Slow enough to understand but quick enough so it's not a 25 min watch! Not just useful for this job but any similar carb disassembly/reassembly. Keep it up!

nice thanks a lot

Very helpful video Keep up the good work

Good video. Thanks.

What’s up man. Great video. I’m getting 90v through my brushes. What would cause that?

Briggs & Stratton generator ran out of gas under load, upon filling and restart, (which I believe was done under power) it blew several control boards on appliances, garage door openers etc…. Voltage tested properly from generator, but lights were coming on and off, as if AVR was toast??? What do you think?

Outstanding I understood ever detail on how to test my cat 8000E. Very clear and cool way to do a youtube everyone needs to watch this guy is great. Thank You

Great info thanks for your help sir

You did extremely well. This was the best video for troubleshooting generator motors.

My brother I have a generac ET 2400 generator and I need some help on how to connect the capacitor, I don’t want to just connect things that I don’t know much about. Can help me on that?

Great video, so I tested my brushes output and I'm getting 70 volts AC. Rotor is toast I guess?

thanks !

Good review. Thank you.

Good explanation except the out put voltage on the excitation windings.e.g between yellow + yellow and Brown+blue.Also want to know how t bench test the AVR.Contact me on smithivan772@gmail.com

Wow! Great teaching. Thank you Kind regards, Craaig

i need a head gasket an manual model 8055 titan diesel generator

Hello there what is the difference between the AVR and the capacitor so is this is considered as a capacitor Or just a voltage regulator?

Excellent video! I have surging power at my outlets on a 2200 watt generator. Produces power for a second, then no power, keeps repeating. When I run 12v to the brushes, everything works as it should... what could it be? Thanks in advance

Thanks. Very helpful

Thanks for the video. I bought the engine shown in this video from someone who said the generator he had broke and he had taken the engine off, given the electric start motor to a friend, and sold the engine (to me). I hear it's very common for these generator ends to fail, and knew there wasn't a lot involved with fixing them. Of course, I'm happy I got a reasonably priced engine. :D Question -- is this unit really made by the LCT/Liquid Combustion Tech company, or is it just a Chinese knockoff using a well known company name? Reason is, I could not find any mention of this diesel engine on the LCT company website. Also - does this engine come with a flywheel-mounted DC charging coil for the electric start battery, or is the engine-mounted voltage regulator powered from the generator end diodes? I can't see any wires coming from where the charge coil is normally installed, and have purchased a new charge coil and permanent magnet rotor to install to allow the engine to keep a starting battery charged since I've re-purposed the engine for use on a wood chipper. The engine has a DC voltage regulator attached to it, but the leads had been clipped and I didn't see the 2 leads coming from where the flywheel rotor is usually installed, so I'm going to have to pull the flywheel anyway, but was just curious if they normally tap off the exciter coil/diodes to avoid the need to install an engine-mounted coil. Thank you for showing how to fix the generator end. I have a gas powered Winco generator which is having trouble starting motors far below the rated power so think I may eventually troubleshoot that unit using the info you presented here. Much appreciated.

Great video. I learned a good bit. I have a generator that shakes like hell when the capacitor is hooked up but runs smooth when it’s out. It’s a brushless gen end. Anybody had a problem like this?

Hey Tyler I need a little help. (Great vid btw) my portable generator is a 12,000 watt 120/240. My question is can any generator of this type (no switch to transfer from just 120-120/240 volts it’s always 120/240) however what’s the reason they tie all the common wires on the r1 stud and can I re wire mine So all the common wires are on R1? And if I can what can I expect as far as performance I.e. wattage , volts , etc P.s. it is, an AVR style generator like yours in the video. Thanks so much for any input or help you can offer. Thanks Tyler

So, the AVR is actually regulating the main AC output voltage, by regulating a DC voltage that goes to the rotor coils ? You put 12vdc to the rotor coils, that resulted with 57vac main output. So, I'm assuming about 26 ish vdc to the rotor coils , would create the desired 120 vac ? I would be curious to see the actual voltage the AVR sends to the rotor coil. BTW, Great video.

Good video - suggest you could say a word or two about the new choke - which way the lever should be when starting, etc.

well done! if you ever want hvac instructions just let me know.

Hello MacleTech, If I understand this right, the rotating field in a brushless gen has 2 sets of windings? one set sakes in a.c. sent to a fw rectifier bridge and sends d.c. to the other winding? The capacitor is used to hold a charge on the stator windings so rotating field will have a voltage induced in it when it starts to spin, that a.c. is turned to d..c to make a stronger field for the generator to build up.

Thanks a lot for all this really useful information

Hi there can you tell me how the power gets to the rotor winding and what those diodes do and what there connected to? and how its regulated from Fred in England

Thank you very much I learned a lot

Best step by step generator diagnosis video so far and I've watched a few.

Hi. What about the "S" conector, two wires come from there, same like the capacitor but those cables goes to a black box to the main panel. Any idea of the fuction it has?

Tyler, you are the man, I now understand how my genny works and what can potentially go wrong with it.

Exellent tutorial. However you skipped over how to match your hertz to your voltage and engine speed. For example if your hertz are at 70 and you need them at 60 but your voltage is 120 @ 70 hertz. when you adjust your engine speed down to 60 hertz now you have 105 volts or so. I liked your video it was spot on.

Thanks! Good explanation!

Great information shared here, thank you

Also..if you have a working generator it doesn't hurt to take the cap off and record the ohms of the stator with a sharpie on the generator housing for future reference.

Some generators of the 'BRUSHLESS' have a rotor with double windings, connected together by a set of diodes or rectifiers/bridge. The rotor spins within a slight magnetic field building up alternating current which in turn is changed to D.C. and creates a powerfull field on the 2 faces or poles of the rotor. As you know, a diode prevents current flowing in one direction, yet allows in the other direction, like as my friend Taryl says, an electrical check valve. The fixed winding/s are known as the 'ST8or or Stator, the part that turns is the revolving field known as a rotor. This whole assembly is in ways similar to the alternator in a car. the rotor here being of 2 poles only while the rotor in the car has a number of toothlike poles, but then again, the car alternator is delivering 3 phase power and changing to D.C. by means of the bank of diodes. The AVR here is similar to the voltage reg. in a car, the lower the btter gets due to the load placed on it, more field is applied to the rotor thu, yup the sliprings. No matter how many KW at a given voltage, over-curent must be avoided, that is why fuses or circuit breakers are employed.

my same generator starting no problem but no out put power,,please solve this problem

That young man was a very good explanation of the troubleshooting of the generators that I have ever came across. Clear and concise. Thank you for sharing your knowledge of these units.

Mr. Tyler, it was great to see you in live demonstration. Finally and late to get back to 5500 diesel generator repair. Installed the tank valve. Good information on troubleshooting my low voltage on generator. I will see to it and get back in touch. Hope I won't need any diodes.

thank you for the information sir.

Good video! Are you still replying to comments????

Are this good generators? You know compared to like a Honda??

I have tahoe industries ti7000lxr diesel generator. It runs 10 to 20 seconds then shuts down. Voltage is 10 volts or so low. Runs fine until flip breaker with no load. Replaced capacitor with cheap on with no change. Any ideas for me.

Thanks so much for this video. The manufacturer sent a diagram with a brush holder so I knew trouble was coming. You are the man.
