Dual Field Alternator Conversion - New Electrical Gremlins!

If you unhook the ignition switch, that is remove the connector, this goes away?

Is there added / modified wiring in the car?

What do you have for a service manual / wiring diagram?

Correct, even with the ignition switch unplugged there is voltage to the coil. I have no other modified wiring. That's why I purchased a resto dual field harness. I wanted to be sure it was all correct.
