65 Dart Instrument Voltage Regulator Tips

I've already checked the board, bulbs and socket and they do work, and I know the dimmer switch works, I'm going to be replacing it since it does not dim very well, it has dead spots and cuts out pretty often across its sweep.

I'm currently adding a ground wire to eliminate that as a variable, and once that's in place I intend to check the voltages at the pin connector and see if I'm getting anything there.

I've checked continuity from the connections at the bulkhead connector and there's no issues there, and I had continuity from the black wire of the ammeter to 2 of the fuses in the block.
