Overcharging Issue & Car Start Issue

I did some troubleshooting today and this is what I found.

I called the individuals who rebuilt my steering column. I asked the if they could make some continuity measurements on the ignition switch wiring harness for the 1970 Duster. They said that they had new one and they would be glad to accommodate me.

This was my findings:

I disconnected my ignition connector on the steering column from the main wiring harness. I place the ignition switch to the 2nd click (Run position)

Taking a volt ohm meter to make make some continuity checks I made measurement from the Red wire to the IGN1 (Blue) and had no continuity. The new cable showed continuity.

Taking a volt ohm meter to make make some continuity checks I made measurement from the Red wire to the IGN2 (Brown) and had continuity. The new cable showed no continuity.

I think that this is the reason that the car will not start when the key position is placed to start but will start when the key position comes back to run (IGN1)

I'll be receiving a new harness in a few days in the mail to confirm this. We're almost 100% sure that this is the problem and a new ignition switch is the fix.
