Well, that at least answers our question about what is grounding the 23 wire... I would try one last thing and remove power from the PCB by removing the 15A fuse located near the bottom corner of the control panel inside. See if we don't just have some glitch in the board holding the relay in.

If that doesn't fit it, it sounds like it's time for a new board :sad:

The controller for that unit is here: https://shop.gentekpower.com/products/g ... roller-pcb

I actually have one that I used for testing one time and then put it back in the box. I can check and see if I have it still. It was from a few months ago, but I'd make you a good deal on it since they don't get replaced often.

Removed and replaced the fuse. No difference, so I guess it is board time.

Model is QT02724ANAN Serial 5083645.

The "test" board would be fine. Actually, I would like to get two boards.

It has failed once before and no one local stocked it. Had to get one online and fedex in. Unfortunately, the generator won't run when needed.

let me know the best way to pursue this? Just order online, or call?

Regards
Mike Serafin
