generator weirdness

[worktohobby]

Dave,

On my bus it is in the same compartment as the generator Fan. If
someone can flip the auxilary battery switch on and off you should
be able to hear it clunk on and of (no engines running). Also, you
should see the genset voltage jump to the coach voltage when the
switch is held in the on position, or you have issues with that
relay as well.

It will simply be a metalic relay, can style, with a self reseting
circuit breaker near on attached to it and a small diode, nothing
special. If yours is like mine, I THINK it is. On my 1980 FC it was
located under the step, no breaker or diode though.

Got to get back to work.
