Ignition System: Description and Operation
There is only one mode of operation in this
ignition system. The
PCM sends timing signals to the IC module. The IC module will then amplify and send a signal to the
ignition coil which will produce high voltage secondary energy. This high tension voltage will then be distributed through the coil high tension wire, distributor rotor, cap, and plug wires. Since the
distributor has no influence on the base timing, adjusting the distributor will not change it. However, the distributor on V8 applications can be adjusted to eliminate the chance of crossfire at the distributor wire terminals. Distributor terminal crossfire may cause poor performance. The V6 engine applications do not use an adjustable distributor.
