Appreciate you letting me cancel my order (ebay yesterday) for the wrong control board, you guys are on my 5 star list!

Just got your replacement board for my 4K Onan, which would only run when the starter was depressed. It was showing a #45 error code. After installing your board the generator started right up and is making good electricity. Thanks!!!

I am watching this video to see how to remove the control board because it is in the way of me cleaning the ground wire that is sparking and causing my generator not to turn over. I think this happens a good bit in older generators.

I removed my 4000 yesterday and today I find this video.

What are symptoms of bad gas control board

I have a 4000 spec P ONAN in my class c.the generator runs fine charges the batteries but when i turn on the AC it sputters and turns off. i can run the generator for hours but as soon as i add extra load water heater and the fan in the ac it shuts off. i can dump the extra power and it starts right back up ???

do they go out ever?

My generator run 20 to 30minutos and lost signal to carburador sol

The control board send volt to carburador sol

Is the control board and voltage regulator on an Onan Microquiet 4000 the same unit??? I have the same control board as in this vid. I just don't know where the voltage regulator is located. My genny won't stay on when I release the start button. It will stay on for about 10 seconds if I hold the start button pressed in. After that, it will die and throw code "3-2".

What are the symptoms of a bad control board? I am chasing very bad voltage noise & distortion (DIRTY power) and can't seem to find the source. New brushes and slip ring cleaning did not solve the problem.
