Thread: 3 Wire Alternator swap help

Tweet

I am currently dropping a GM V8 into my 60 Bel Air that had an I-6. I am going with HEI and a 3 wire alternator. I have been researching the hell out of my wiring options and am trying to figure out the best way to rig up the alternator.

From my understanding (and please correct me if Im wrong) these are my plans:
-The positive lug on the alt will go to the postive lead on my battery.

-Spade connector 1 on the alt will go (in series) first thru my old generator light on the dash, then to switched positive lead on my fuseblock or ignition switch.

-Spade connector 2 on the alt will go to a positve connection on my fusebox or a positve junction.

I do not plan to jump #2 to the positive lug on the alternator. Though I know this can be done, I have read that the #2 is a sensor and needs to get an actual reading of the voltage in the harness. If I jump #2 to the lug, I get an incorrect reading causing the alternator to not energize enough to fully charge the battery.

Please tell me if I am on the money here or where I may be wrong. How did you do yours?

Thx guys!
