Ignition Coil & Power Transistor

WARNING: This page is about a different variant/trim than selected.

The power transistor switches ON and OFF the ignition coil primary circuit according to the ECM signal. As the primary circuit is turned ON and OFF, the proper high voltage is induced in the secondary circuit. The distributor is not repairable except for the distributor cap and rotor head.

NOTE: The rotor screw which secures the distributor rotor head to the distributor shaft must be torqued properly.
