What is an ignition ballast resistor?
What is an ignition ballast resistor? The ballast resistor allows the ignition system to operate at a lower voltage until the engine starts. The ballast resistor then functions to regulate the voltage going to the ignition system to avoid additional wear on the system. What does a resistor do on a ignition coil? In simple terms, the ballast resistor in a Mopar limits the amperage, or current flow, through the coil while the engine is running, thereby extending the life of the coil and breaker points of the distributor.
