On some systems the "12" volt coil is not twelve. It is actually an "8" volt coil. The ballast resistor is needed to keep things from blowing up. When you turn the key to start and the solenoid closes that extra post on top shoots straight power to your coil. Now as the starter starts to turn it is sucking the 12 volts from the battery down to 8 volts. This hodge podge lets your coil have a really good spark. When the engine starts and the solenoid is now open, the resistor is in line and with 12 volts going in and 8 volts coming out to the coil. Sounds nutty but it works. Anyone else have something to add? Far as I know this is how they work.
