Starting System -- Evolution: General Description: Notes
If the ignition switch is turned to the "START" position, current flows in the coil provided inside the magnetic switch, attracting the plunger. When the plunger is attracted, the lever connected to the plunger is actuated to engage the overrunning clutch with the ring gear.
At the same time, attracting the plunger will turn on the magnetic switch, allowing the "B" terminal and "M" terminal to conduct. Thus, current flows to engage the starter motor.
When the ignition switch is returned to the "ON" position after starting the engine, the overrunning 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.
