Manual Transmission
The starting system consists of the:
^ starter motor
^ starter switch, part of the ignition switch
^ Clutch Pedal Position (CPP) switch
^ starter motor solenoid relay switch
^ starter solenoid
^ starter drive
The starter motor:
^ is a permanent magnet, gear reduction, 12 V DC motor.
^ has an integral starter solenoid.
^ has an over-running clutch in the starter drive.
^ is serviced as an assembly.
The starter motor solenoid relay switch:
^ controls current to the starter solenoid.
^ is engaged by the ignition switch.
^ connects the battery to the starter motor.
The Clutch Pedal Position (CPP) switch prevents starter motor engagement unless the clutch pedal is pressed.
The starter drive:
^ is operated by the starter solenoid.
^ engages the flywheel to turn the engine.
^ has an internal over-running clutch to disengage the starter motor when the engine starts.
The starter solenoid:
^ is an electromagnet.
^ engages the starter drive to the flywheel.
^ when energized, the contacts close, connecting the battery to the starter motor. This causes the starter motor to turn the starter drive.
^ is kept in the energized condition by a hold-in winding until the starter switch is released.
When the ignition switch is turned to the START position, the starter motor solenoid relay switch is energized, connecting the battery to the starter solenoid. The starter solenoid moves the drive lever and pin to engage the starter drive with the flywheel ring gear and connects the battery to the starter motor.
Clutch Pedal Position (CPP) Switch
The Clutch Pedal Position (CPP) switch is controlled by the clutch pedal. Depressing the clutch pedal manually closes the CPP switch and allows engine cranking. The CPP switch will also deactivate the speed control system.
