I must disagree. Ballast resistors were used regularly on cars with ignition points. There was always a circuit through the starting circuit that would bypass the ballast resistor so you could get full voltage for starting but the ballast resistor was meant to reduce the voltage once the car started to limit the wear on the points. On the Delorean there are TWO ballast resistors. When starting one is bypassed by the relay under them on the firewall.
