72 Cheyenne Super Alternator Wiring

[Cam1968rsss]

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

The newest install I could find is from a '70.

In that drawing, that sure looks like a Pontiac V8.

it probably does look like a Pontiac V8. But it you look in 1972 C10 assembly manual, allot of the small block pictures are drawn looking like a Pontiac V8. Thanks for sending me that picure helps allot.

This is a 67-72 Chevy truck forum.....that drawing is from the 67-72 Chevy GM truck assembly manual, so maybe they stole it from Pontiac.

They weren't stolen from Pontiac. Pontiac hacked their way in and substituted the drawings to plant subliminal messages in the minds of Chevrolet customers.

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.

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.....

LockDoc ! That is exactly what is happening . I am going to retake with smaller pixels and see what happens. Thanks for the tip

That and the speed of your computer and the local internet connection. I had century link though the phone company and could only load one photo at a time and kick me out if I tried to load two or more. Now I have T mobile and I just uploaded these four images and poof they were uploaded. Some of the show coverage photos I do used to take hours to load just the truck shots on here or load a Photobucket or Smugmug album.

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.

Cam1968rsss, per your previously sent messages. After a bit of digging around we ended up finding an OE 1972 p/n 1102455 (2 F 7 = June 7th 72) alternator stored on the shelf and the alternator still had the below pictured 72 specific wire harness retainer bracket and mounting bolt attached. There is no spacer needed for mounting as the 72 style harness bracket mounts directly to a threaded standoff boss w/machined flat on rear of alternator, the smaller 71 and prior style alternator wire harness retainer bracket mounted to the ground stud on the rear of alternator, this grounding stud is not used/found on the 72 style 42 amp p/n 1102459 or 61 amp p/n 1102455 alternators. We have listed both the 72 harness bracket and alternator separately in the below linked f/s thread and given you first option/right of refusal, have a look and confirm in thread. Thanks for your patience in standing by while we dug this one up for you, Mel
