The negative wire attaches to the power supply and the positive wire goes to the distributor/points. Light bulbs will work with either polarity, as will starters, relays, and heater blower motors. However, the radio and ammeter gauge will not; they are polarity specific.
When is a positive wire hooked to a negative wire?
This means that the wire hooked to the red lead is positive and the wire hooked to the black lead is negative. If your multimeter has a negative reading, like -9.2 for example, the leads are reversed, which means the red lead is hooked to the negative wire.

What’s the best way to replace an electrical terminal?
Place the hooks so they point in a clockwise direction and the insulation runs all the way up to the screw. Don’t leave any bare wire between the terminal and the insulation. Tighten the screws to clamp the wires down. The same goes for clamps that are tighten over a straight wire, there should be no bare copper showing.
