Electronic Ignition System

Mitsubishi breakerless electronic ignition consists of an ignitor, ignition coil, pick-up coil and distributor. The control module is mounted inside the distributor with the pick-up coil assembly.

When ignition is on, ignition coil primary circuit is energized. As distributor shaft rotates, the reluctor rotates inside the stator assembly.

As armature teeth pass pegs of pick-up coil, a signal is sent to the ignitor. The ignitor then breaks the primary circuit in coil, causing high voltage surge in coil secondary circuit required to fire spark plugs.
