Starting System: Description and Operation

When the ignition switch is turned to the "START" position, current flows in the Pull-in and Holding coils inside the magnetic switch (starter solenoid), attracting the plunger. When the plunger is attracted, the lever connected to the plunger engages the starter clutch and completes the circuit between the "B" and "M" terminals, providing current to the starter motor.

When the ignition switch is returned to the "ON" position after starting the engine, the starter clutch is disengaged from the ring gear.

An overrunning clutch is provided between the pinion and the armature shaft, to prevent damage to the starter.

Operation
When the ignition switch is turned to the "START" position with the selector lever in "P" or "N", the solenoid (magnetic switch) of the starter is switched ON and the starter motor is activated.
