(2001 Ford E450 Coachman Santara) I recently changed the fuel pump and filter on my Onab 4000 micro quiet generator. I disconnected the battery in the cab and not the coach ( not thinking) and had a quick arc from the main line in the area of where the solenoid would be. I finished my installation but now I have no power to the coach or to my generator at all. I'm stumped. Any suggestions ill be greafful.
