Electronic Ignition System

The Hall Effect sending unit in the distributor uses a shutter window wheel mounted on the distributor shaft. The shutter blades pass in and out of the air gap of the hall effect sender resulting in signal pulses. There is one shutter window for each engine cylinder. Signals from distributor hall sender are sent to the ignition control unit. The ignition control unit sends a switching voltage signal to the ignition coil primary circuit to discharge secondary spark voltage.
