3G alternator

Are the regulator's interchangeable in these, meaning can you just buy a new one? Mine quit charging today on me. I guess I will go to the pick a part and find one for now, but I'm not having much luck finding a good one.

Not quite sure what you are asking, the voltage reg is internal to the alternator. If a tester is saying the reg is bad, then replace the alt, or tear down the alt itself and inspect, and repair or replace.

They are replaceable, just match the color of the case, normally grey. White is PCM controlled.

I was just having a hard time locating another alternator, there is a guy here that hoards them by the wheel barrel load and restoring sells them.
I got lucky this am and found a car that they couldn't get the hood open on and scored one.


I learned a hard lesson. I am a couple hours from my shop and had no access to my parts stash. I ended up blowing a mega fuse when my alt went, but didn't realize it at first because it looked fine. Being that I had put the Painless 3G kit in my truck, I had no access to another fuse that size. The Painless mega fuse is half the size of the Ford one, and nobody sells them here. I ended up buying a new mega fuse holder at Napa and putting a Ford mega fuse in so that in the future if one goes I have access to parts anywhere. I will be pulling that Painless fuse holder out of my Torino when I get home and mounting one of these in as well.
