 I went out and measured my ballast resistor and it was about 2 ohms resistance with nothing connected to it.

The ballast resistor is in the loop to reduce current to the coil while the engine is running. While starting, the starter solenoid provides direct 12v to the coil with no resistance since voltage is lower while the battery is taxed with turning the loaded starter motor.

Hope this helps.
