Ignition System: Operation

The Hall Effect sending unit is mounted inside the distributor. A trigger wheel passes in and out of the air gap of the Hall Effect sending unit. There is one trigger wheel shutter for each cylinder of the engine.

The Hall Effect sending unit signals the ignition control unit to make and break current flow in the primary circuit of the ignition coil. Secondary voltage is released through the high tension wiring, distributor cap and rotor to the spark plugs.
