The control board, if there is such a thing
, must be in the generator enclosure. I've had the top off the generator enclosure and didn't see it. There's a few relays near the front passenger side, but not a circuit board that I recall. On top of the generator there is a plastic enclosure that I "assumed" just contained the generator leads as they come out of the generator. Maybe the control board is inside this plastic housing? I know this housing is plastic because I foolishly tried to ground my relay to it.
You probably already know that plastic isn't a good conductor of electricity.
I did too, but the housing looked like steel to me
How were you able to change the fuel pump? On my generator it appears that one must have really long, skinny, and strong fingers or just about disassemble the entire coach
. Well, almost disassemble the entire coach
