Ignition Rotor: Description and Operation

Rotor Resistance:

The resistor rotor is mounted to the front of the camshaft via the rotor adapter. 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. The ignition energy is then directed to the correct cylinder through the ignition wires. A 1K ohm resistor is molded into the rotor for radio frequency suppression.
