12SI Altenator upgrade problem

938 Views 6 Replies 4 Participants Last post by  CHELKAMINO
Did this upgrade 3 years ago on my 71 with no problems. Just did the same upgrade on the 72 Elco and it starts and runs fine, but the motor will not shut off with the key? I have an ignition switch for the MSD box, so I can kill it that way. I wired it correctly and looped the old regulator harness per MAD's web site instuctions.

I have the diode, but not sure which wire I am to connect it to?
I believe I have a blue and a white going to the altenator.
Terminal 1 or 2 with internal regulator?
I got it, wired it inline with the jumper wire I used for the old external regulator harness. Drove it to work tonight with no problems.
