26308Re: Onan generator in 1984 Allegro
- Jan 1, 2007Happy New Year all,,
Since generator questions came up, I have one. On a 67 Travco, I
have an Onan, orginal that is powered from a small 4 cyl flathead
engine. The previous owner said when he went to start it one day
there was a loud pop from around the switch box, or just behind it
somewhere. I have yet to track anything down that may have shorted
out. Is there anywhere I should be looking or something I should be
looking for? It is the 6500W model. I have removed the cover from
the switch box where the toggle switches are and even replaced one of
the switches but nothing.
Thanks for any help
