Electronic Ignition System

Mitsubishi breakerless electronic ignition consists of an ignitor, ignition coil and distributor. The control module is mounted inside the distributor. 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 a high voltage surge in coil secondary circuit required to fire spark plugs.
