Ignition System: Description and Operation

CIRCUIT OPERATION

2.3L

With the ignition switch in ON or START, battery voltage is applied to the ignition coil. As the distributor shaft turns, the igniter acts as a switch to control current flow through the primary winding of the ignition coil. When current flow though the primary winding is stropped, a high-voltage current is induced in the secondary winding of the ignition coil. The high- voltage current then flows through the distributor cap and rotor to the proper spark plug. The radio noise suppressor helps reduce electrical interference.
