6v-12volts?

the main purpose of a resistor coil.... When the key is in the start(cranking) position, the coil is fed directly with the full 12 volts, giving the spark a boost. when the key returns to the run position, the coil is once again fed 9 volts, having been dropped from 12volts, by the resistor.

Actually, when the key is in the cranking position, the Starter draws current and the Batt voltage drops well below 12v, down to around voltage the coil operates on. If this was run through the resistor, the coil would be getting insufficient voltage.
