Glenn,
Good luck on Rochester, we are from there but not in winter anymore. The snow is in Buffalo so none in Rochester.
Had a friend with an older coach on Spartan Chassis with Cummins engine and he had to run around back and short a solenoid every time he wanted to start it. Had a screwdriver he kept handy just for that. Sounds like you have replaced the screwdriver with a switch.
Hope you can find a decent mechanic to trace it out and repair it for. I have used Tracey Road Equipment in Henrietta for routine Freightliner service.
