Pulling my hair out trying to get the old boat to run again. It came with a generator, obviously, and somebody installed a GM alternator at one time with an external regulator. That is great and all, but the alternator died. Oh, and it wasn't charging worth a damn when it was on there. They left the generator harness in and I've got about 1000 wires all over the engine bay. What I'm getting at.... Does anybody have a wiring diagram for a GM 3 wire alternator? I've looked through books, etc. and even searched in here (only found ford 4 wire stuff.) Any help is appreciated.
