Hei conversion troubleshooting

Just so you know. the coil body does not require grounding.
I would run a 12v wire direct from the battery+ to the coil+ and module+ and try it that way.
This eliminates all the old ballast wire questions and gives a known good supply with nothing to cause drops.

Also when swapping to HEI I tie all the ballast wires together at one point.
Usually ign1, ign2 and the regulator (sense) wire blue, and the new coil+ wire.

I have already run a relay so that I'm getting 12v direct from the battery (via starter relay terminal) to coil and ignition module with 12g wire.

I will go back and hook all the ballast wires together. Although, my electrical system was charging properly before I wired up the relay. It is hooked up exactly according to the hand-drawn diagram I posted above. Idk how it could be having an effect on the charging system, unless that coil and module are just drawing that much voltage. That doesn't really make sense though.

If I am showing a 1v drop from battery terminal to the regulator positive terminal, that would indicate that the regulator is working properly, correct? That it is trying to compensate for that voltage drop?
