Working on a Kohler 12.5CCOPY61 out of a bus. Engine is a Perkins diesel that just shot off while running and can't get it to start again.

Anyone have a idea where to get a service manual for it at.

Thanks,
Joe

Barry,
Got it. Thanks a lot.

I ended up finding the service manual on the Wanderlodge site. Turns out they have all kinds of manuals for things they used in their buses.

Discovered that the generator has low voltage...73 volts on 1 leg and 75 volts on the other one. Looks like it either needs new brushes and/or the rotor magnetized. If that doesn't fix it, then it most likely has a bad voltage regulator.

Thanks,
Joe
