For 73 Javelin 360.

What should the polarity be on the S & I posts of the Stater Relay and what should the polarity be for the wires coming out of the Ballast Resistor?

The reason I ask is I'm trying to fix the "clean up" work someone who was helping me install a new coil did. The wires to coil test as ground/negative but I think they should be positive.
