Thanks, Tgoods. Went back the other day armed with a fuse holder and new fuse. The one on this board was a 15 amp fuse. Anyway, soldiered it into the board, and put in the fuse. Plugged it in. IMMEDIATLY, blew fuse.
Then, I unplugged the wires from compressor to try to isolate problem, and found fans were running. Relay was toasted, Replaced the relay, overload and new 15 amp fuse. BINGO. plugged it in, working like a charm.
Saved the customer money, Saved myself from locating and buying circuit board, and I stopped yesterday and picked up 2 more fuseholders to keep on the truck. Thanks again, Tgoods.
Tried to paste the picture in of the board but can't get it to work. If I do, will post pic.
