Just picked up a new alternator for the boat. Its a Sierra 18-5951 3 wire alternator. My question has to do with how to wire it up to the engine. The Orange and black wires are self explainatory, but which wires do I hook up to the red/purple and purple wires coming from the engine harness? The alternator has a black wire and a red wire.
Do I assume that the red wire is colored correctly and that the black wire on the new alternator would have been white on the original? (I never saw the original-I'm replacing an automotive alternator, and I have my doubts whether it was hooked up properly.)
I looked at the manual, but it is still unclear to me. Maybe I just looked in the wrong spot. I looked at section 4C in Manual #10.
Same engine, same alternator, same year, same question. I wasnt aware i needed to start a new thread sorry. It looks to me the red and purple coming from the engin harness goes to the red wire and the purple wire goes to the black wire. Just was looking for some confirmation.
