<VV> 12SI Alternator Question

[Geoffrey A Johnson]

I have been chasing a few gremlins on my 63 coupe.

The battery dies pretty quickly and it never seems to charge.  This is 
12SI with proper wiring and soldered connections.  It uses a GM 
truck junction 
block with a voltage sense wire.  The question I have is....

On most  10SI and 12SI alternators there is a resistor that runs between 
two of the screws that hold the regulator in.   Now I have Bob Helt's 
diagram here and I can not figure out which resistor it is.   Maybe R2 or 
R3.   Anyway it is the first one to come out when pulling the regulator.

Now this one did not have it when I got it.   So I had added one out of a 
parts alternator when I built it.

So which one is it, and does it belong there?   I pulled several apart 
today at the Junkyard and they all had it.   I will do all the other 
normal tests next, just want to know about the resistor.

On a separate note, I rebuilt the starter and made it a nice new soldered 
harness today.   Starts nicely now.

Thanks
