Generator

[dhardy1944]

Thanks George,

However, it is when I hold the switch in that I get into trouble. It usually
will not
continue running and that is when the starter stayed engaged even after I let
go of the switch. On at least two occassions it cranked until I got out of the
bus
and pulled the quick disconnect for the batteries. That must have been a
couple of minutes of cranking and it still did not catch.

Thanks - Dave (84PT40)
