Very Confused!
When the electromagnetic gets some juice, the points get opened. The current to the rotor must go through a resistor.
With more juice, the other points get contact and no juice flows out to the rotor.

Increasing system voltage increases power of the electromagnetic coil.
Off the top of my head, zero. This lets full current flow to the alternator's rotor.
