Electronic Ignition System

The ignition system consists of an ignition coil, a distributor containing a P/M generator crank angle sensor, trigger wheel and rotor, and an ignition power unit which opens and closes ignition coil primary circuit based upon signals from control unit. When power unit removes the ground circuit from the primary ignition, the magnetic field around ignition coil windings collapses. This produces an induced high voltage surge which is used to fire the spark plugs.

Power for the ignition coil is provided through the ignition fuse when the ignition switch is in the "ON" position. Tachometer signal generated by the triggering of the ignition coil is monitored by the control unit on terminal "A12" after passing through a "noise" filter.
