I'm down to connecting the last two wires of the wiring harness onto the alternator of a 1971 580CK. There are two posts.... one large, one small. There are no spade connectors on the wires to indicate size, and it doesn't appear that one wire is any larger than the other. Which one goes where????? I'm afraid I'll fry something if I guess wrong! Thanks in advance for your help guys.

It only has "ALK 7314" 100 stamped on a plate. From that I gather it's a Prestolite. It looks as though the voltage regulator is attached to the center-rear of the alternator, externally, with two wires already attached to the alternator....one connected to a spade connector, the other to the "AUX" stud.. There is a larger size "+" stud on one side of the alternator housing, and a smaller "AUX" stud that I already mentioned, on the opposite side.

I'm afraid I'm not much help on this one. I checked a manual I have and it had only 1 page on prestolite, and didn't help much. Maybe post again and see if someone has some info. AMC used prestolite so maybe an AMC manual about that year would help.

After doing some research, I found a service manual that has a schematic on the ALK alternator system. It doesn't give me all of the info I need, but it does give me enough to "assist" me in figuring out what goes where..... I think!!!!! If you see a warm glow in the skies over Western PA, I was wrong!

Thanks for you replies.

Paul
