I have a Delco/Remy alternator with a one-wire stud in the back, and on top there are two connectors, one is (F)feild, the other is(R)relay(?). The numbers on the casing are1 102480 61. how can I wire this to Chritine? The truck is wired like a race car. one toggle switch for current(start,power), one toggle switch for starter. I need Chritine on the road ASAP, I start a new job tuesday morning,6:30 am, easterrn. :confused:

Doc here, :pimp:

This is the way GM does it:


  • 1. This is the main power wire that goes directly to the battery. Make sure it is a heavy gauge since it has to carry the full output of the alternator (up to 100 amps).


  • 2. This is the field wire that energizes the alternator. It must be switched, or else it will drain the battery overnight. Do not wire this into the coil power wire that you use to switch the engine on & off , since once the engine is running the alternator will feed power back through this wire, which will then power the coil, & you won't be able to shut your car off.


  • 3. This is the lead for the sensing wire that goes to the idiot light in your instrument panel. When this light lights up you know that your the alternator has just stopped charging.

You Should be able to apply those outputs to your Ford wiring..

Doc :pimp:

Hey thanks for info :D One question- the idiot light terminal, do I have to wire this terminal, or just the main power and feild wire? the harness is snafu, but I do use the key switch for electric fuel pump(thru the aux fuel fuse, and two power the lights,etc :sweat:

Doc here, :pimp:

Wire the lamp up to the old lamp circuit wire.. might be a brown wire on the old regulator..

This wire goes through the lamp, a bypass resistor, fuse and on to the key switch. (on a GM Ford should be close..)
