Luxury Coach Lifestyles - View Single Post - 12.5 KW Kohler Diesel Generator Won't Power AC

Cliff: since my wiring diagram is at the storage lot I'll have to pull this out of my head (not the obvious other place). On my 77 coach with the 12.5 Kohler the inside switch and the one on the control box on the generator are wired in parallel, so if either is "on" then the generator should be "on". If it loses the "on" circuit I believe it will shut down.

I don't have the information with me to give possible explanations for the lack of AC. This vintage of gen does not have the blower the later models have so that source can provide no information.

Hopefully I'll get to the storage lot tomorrow and be able to give more insight
