I'm having trouble getting my charging system to work properly. My alternator has been checked a couple of times and is good. It is an externally regulated unit. The Pontiac wiring diagram has a 2 wire hook up to the regulator, but the '63 Impala diagram shows a 4 wire hook up with an "idiot" light in the system.
Does anyone know if I can use the regulator from the Chevy diagram and hook it up with the Pontiac 2 wire system? The Chevy part is much easier to get.
The Pontiac is different because of the ammeter... you need the Pontiac regulator... OR, if originality isn't an issue, install the internal regulator alternator, jump the brown and blue at the regulator, and use the blue at the alternator as terminal 1... you will need a jumper wire from terminal 2 to the post on the back of the alternator....
Nope... I have done it with most of mine... this is my '66 Chief... I remove the existing brown out of the connector and pop in the blue from the original harness..
So just so I understand:
You take the blue wire that would originally go to the "F" on the regulator and attach it to the brown that would originally go to the #3 on the regulator so that when the ignition is turned on, you get 12 volts through the brown into the blue and into the #1 terminal on the internally regulated alternator.
You also put a 10 gauge red with constant battery voltage to the #2 terminal on the alternator.
Is that correct?

I apologize to the moderator. After looking at the site more thoroughly, I saw that I should've posted this in the "General Electrical Forum". Please excuse my newbie - ness.
