Ignition Rotor: Description and Operation

Ignition Distributor:

The resistor rotor is mounted to distributor shaft. The distributor cap and rotor are aligned so that when an ignition impulse is generated by the coil, the rotor points to the appropriate terminal of the distributor cap and the ignition energy is directed to the correct cylinder through the ignition wires. A 1K ohm resistor is molded into the rotor for radio frequency suppression.
