1965 Dart Charging System Question

I've done some more playing around. I ran a new section of 14 gauge wire from the ignition switch to the bulkhead connector, and I ran new wiring from the bulkhead connector to the ballast resistor and the voltage regulator. Here are my new numbers:

Key on, engine off:
Battery: 12.2V
VR: 11.6V
Ballast resistor: 11.6V

Key on, engine running:
Battery: 14.0-1V
Alternator: 14.3V
VR: 14.0V
Ballast resistor: 14.0V

It looks like I might have some voltage drop somewhere in the battery circuit under the dash. The ammeter connections are good, but any of that wiring, including the welded splice, could be a little worse than average. I think I'm going to leave it alone for now; it seems to be functioning pretty well.

The best thing is that it's idling a lot better now (which could have also been a high resistance ballast that was on it). I'm running an aftermarket orange box on it right now, but it's always had a light idle miss since I've been driving it, even with points and several carburetors. I think I might have just had a lot of resistance in the primary ignition circuit. Thanks for the help, Mattax.
