How to fix voltage regulator for cummins 3000 watt generator

Most of the time it is the AVR that has blown. Check out our videos on how to test them.
We hold your AVR in stock and have a whole Help Center dedicated to helping people fix their Portable Generators. Check it out on our site. https://www.generatorguru.com/

THERE COULD BE SEVERAL CAUSES; THE VOLTAGE REGULATOR, THE CARBURETOR, THE OIL LEVEL. ALL NEED TO BE CHECKED.

Did you get this fixed? this is an old post. If not visit www,advanced-power-technologies.com (Cert Cummins Dealers) They can answer your questions.

Most likely, rotor slip riings, brushes, control board (if no stator output)

dear see that :
1- the range of voltage which inverter work between it for example 180-260 v
2- most small generator voltage reach more than 260V so the inveter not work
3-check the frequency of genaratoer if it not fix the inverter will mot work

Is it losing Battery power, or just not pumping? check connections, and pins on board connector. Failing that replace the board, if Battery voltage is been lost

Hi there dirty plugs or fuel system

I would check spark arrester and clean it and the muffler first.lt could be the inverter unit. If you have a meter determine the output voltage, and freq. You would need a scope to look at waveform the repair should be lest to a repair center. suggest you call Honda for more guidance.
You could spend a lot of money on maybe parts./

sounds like a voltage regulation problem with the generator

wow, that is high, i would think voltage regulator is faulty also
