Awesome video! Very helpful and appreciate your hard work to put this together!

Thank you very much for making this video. I have a Westinghouse that has served me well. We just lost power for 15 hours, and for the first time the microwave sounded odd, and some led light were flickering. When power returned I checked the voltage. 315 across the 240 hots. Got a new avr. Hope that does the trick.

Good man ! YOU did everything, correctly, sir. i been studying electronics/mechanics for years. Fix these, now i am 'retired' . (on paper, anyway). Good choice, of replacement AVR. ALWAYS REPLACE the factory one, with one with REAL METAL, ON THE HOUSING, FOR A HEATSINK. i even add heat sinks, on new ones, which DO NOT have a sink, on the transistor/FET/ IGBT tabs...... . Good boy, show them engineers, 'how its' done '' correctly. from Alberta Canada

Thanks for this. I am also in South Africa and have a small Stramm generator of 1.1 Kva. It also is blasting out 300 or more volts and blows lights and computers if I dare use it! With our present "load shedding" happening daily, I know now what to do - thanks again!

Thanks. I have the same problem with my Ryobi 5kW generator. Thanks to you I know where the AVR is located. Of course things always break over the Christmas holidays, but I have ordered a Grip AVR from Builders Warehouse on Boxing day, for collection tomorrow 27 December. Holding thumbs that it will work! I know that there are cheaper options, but those companies are closed and will only reopen on 3 January.

Update. It is working fine now! The k generator kept cutting out after less than a minute, but that was because the engine oil level was too low. I topped up the oil and now I'm ready for Stage 3 loadshedding again.

Love your videos.... thank you for the passionate tutorial Do you have a fix for extending the exhaust of a portable gene?

i went to the guys on the street who do exhaust repairs and bought a thin tail pipe. I put it over my pipe and enclosed the genny in a small room with fans. Worked like a charm.

Thank you just have a question I have replaced the blown AVR with more than 300v with a new one just to see smoke come out of the new AVR that was replaced can it be the alternator that keeps blowing the AVR?

Hi thanks for this video from South Africa, I miss the “tortel duiwe” in the back ground :) I bought a light tower generator at an auction, it has a 110V and 230v plug (Canada) the voltage is close to the above rated voltage till you plug something in or turn the light tower lights on, it will jump to 340V and stay there till you switch the lights off. It’s a brushless generator with just a capacitor to regulate the voltage, it’s just weird that the voltage is all over the place under load, it seems that when the capacitor is gone it should have low or no voltage, instead of high voltage.

thanks. its not regulating for some reason. Does the rotor change speed when you load it?

@skidoorider66 3 жыл бұрын

No it doesn’t, the engine runs at 1800 rpm. I replaced the capacitor, with same one (25mfd and 450v) and it still the same.

Thanks you for sharing this . I have a similar problem with my gen set carrying an 8 wire regulator . I don't know how to wire the regulator since it has the 2 wires for the brushes , 2 blue wires and has a plug with 3 x red wires and 1x white wire . I connected the other wires that were fairly easy . I had a plug with 3 x yellow wires and 1x green from the gen side . After modifying the plugs i connected the 3 reds to the the 3 yellows end the whit to green . Still pushing out way over what it should . I sent the gen in for diagnosis but the tech said the avr is unable to adjust the voltage right . Could i have connected the 3 red wires wrong ? I am a bit baffled by it and don't know how to test the regulator . Could you give some advise ? It will be greatly appreciated .

We need to know, that generator part / model number, as well as that Regulator, wattage and brand/make/model. Year of manufacture. Thanks....

Is it possible to have a faulty AVR adjustment potentiometer? My generator is at 250V but no matter how many times I turn the screw, it makes no difference to the output on the generator.

I have a clone generator,and increase for a 2 second rpm and the generator get overvoltage and stop.any ideas?

So I have a Honda em5000s model and I am having the same issue with mine I have replaced two regulators on mine and I am producing 168 volts on the 120 volte setting and 330 volt on the 220 volt setting any help is appropriated. I have check the generator head and everything is checking okay.

Ek het n Linz Electric Alumen SB alternator in my 230v enkel fase generator. Hy het geen voltage regulator. Hy maak gebruik van n kapasitor om sy voltage setup te doen. Sy kapasitor het gegroet en gee my 400V in plaas van 230V. Het al 4 ligte geblaas op my ligtoring van R16000 per lig.
