hey guys a buddy and i just finished up a 12v its a 97 and the truck is a 91 f250 . I would like to figure out what people have done to get the ford wiring harness to work with the dodge alternator. thanks for any info.

 

I saved this off of another post I do not know the author







Its common for the pcm to go bad a make the alternator not charge. I got tired of i and figured out how to use a ford regulator and make it work without the pcm.

Part numbers:
OE #9PZ10316A, E2PZ10316A, GR433, 544A, 540B

The regualter has four prongs (IASF) but only use three ASF.

Wiring

First find a spot to mount the regulater.Be sure the regulater is mounted grounded good before you turn the key on. (I mounted mine above the pcm)

A-goes to the +battery cable on the alternator (Large post)

S-goes to the ignition switch or wire thanks hot when the key is on

F- goes to one of the smaller post on the alternator (it doesent matter which one)

Be sure to unkook the two old wires on these small posts

On the other smaller post hook a wire on it than hook it up the the ground on the alternator
