1965 Dart Charging System Question

Just follow the "road map." It might be right in the ignition switch contacts / ignition switch connector. Don't get distracted by such as the alternator unless there is some other problem. Concentrate on the two end "subjects" and what is in between..........that is, the battery, and the VR. Follow that specific path. Is it the blue "igntiion run" terminals in the bulkhead? Is it the igntiion switch connector? Is it the switch itself? You can access the switch, so you can check it fairly easily.

I just replaced the switch and lock because the old one was loose, so we can rule that out (since the voltage drop got no worse and maybe a little better). I also rewired IGN. 1 from the switch out to the VR and ballast resistor. I really think the only thing left in that circuit can be the battery hot wire from the splice to the ignition switch. I think I checked that one yesterday (at the switch) and it was low, although I didn't make a note of it. That wire will be a bear to deal with in the car.
