Starting System: Description and Operation

GENERAL INFORMATION
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
- For models equipped with M/T, the clutch pedal position switch contact is switched OFF when the clutch pedal is depressed. When the ignition switch is then switched to the "START" position, electricity flows to the starter relay and the starter motor, the solenoid (magnetic switch) of the starter is switched ON, and the starter motor is activated.

NOTE: If the ignition switch is turned to the "START" position when the clutch pedal is not depressed, electricity flows to the starter relay (coil), the clutch pedal position switch, and to ground. This causes the starter relay contacts to remain open, preventing starter motor operation.

- For models equipped with A/T, 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.
