Ignition Rotor: Description and Operation
Distributor Rotor (13)
The resistor rotor is mounted on the distributor shaft which rotates at the rpm of the camshaft. 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 1 kOhm resistor is molded into the rotor for radio frequency suppression.
