72 Cheyenne Super Alternator Wiring
Hi, would anyone have a stock (or restored) 72 c10 with a stock alternator hookup that could take a pic of how the factory wiring is hooked up? my wiring harness has a small mounting bracket in the harnesss that connects to the back of the alternator and I just wante to hook it up the right way. Thanks

Re: 72 Cheyenne Super Alternator Wiring
The newest install I could find is from a '70.

Re: 72 Cheyenne Super Alternator Wiring
In that drawing, that sure looks like a Pontiac V8.

 Or it could be that since the Pontiac V8 came out a year earlier than the Chevrolet V8 Chevrolet saved some coin and reused the Pontiac drawings. And at that point in time GMC was planning on using a Pontiac V8 in their truck.

Re: 72 Cheyenne Super Alternator Wiring
 1972 is a one year only alternator. Think of it as a hybrid of a 1973 12SI and a 1971 10DN. The 1972 uses the case of the 12SI but still requires an external voltage regulator like the earlier 10DN. The easiest way to identify a 1972 alternator is the orientation of the electrical terminals.

If you are getting a "Security Token" message that means that your pictures are too big and you need to size them down. I size all of mine down to 1150 pixels wide and the board software can handle them from there.....

This is a little tutorial I made back when for loading photos but I would upload one at a time and maybe two to see what handles as far as uploading without the computer, net or site having a hissy.
