So I think it has something to do with the Mallory unilite ignition I added years ago. I think it may be bypassing the resistance wire so the distributor gets a full 12 volts. Not sure why it is connected to the ground though and not to the + side of the coil. I'm also running a ballast resistor instead of the resistance wire. Wish I could time travel back to 1994 when my uncle helped me install this and see if he could explain it to me. I guess it doesn't really matter since the car runs, but I would like to understand exactly what the deal is.
