Wiring problems (to Generator)

[Hurricane993]

I've looked at all the wiring drawings I can find and can to figure out the start circuit on my 1994 Vectra 34. It shows the plug and where it plugs into the gen and the plug behind the fuse block under the hood. The starter solenoid went bad and then the starter, got them changed out but something happened and now I have no 12v starting power to the gen. My son in law said he kind of touched the + to the solenoid and there was a spark. I still have the 12v at the solenoid. Can not find a fuse or circuit breaker any where for the 3 green and 1 purple wire that plugs into the board. Thanks

Put a tracker on and all the wires seem to be OK to the front. Have not pulled the dash apart to see if there is a fuse or circuit breaker there.

OK, I think the power for the start stations come from the control board on the Onan generator, right? so I need to figure out the Onan wiring not the coach?
