Thanks so much for your willingness to help. Actually, what it
turned out to be was a broken solder line on the back of the circuit
board. I, Des, can't tell you from where to where because Les fixed
it, but I think it was from the fuse to one of the terminals. I know
instead of trying to run a new solder line a friend (who does a lot of
electronic work) had Les solder a wire from one end of the break to
the other end of the break. Our generator works like a charm now.
Thanks again,
Les & Des
