Starting System: Description

Bosch and Melco starters use a planetary gear train that transmits power from starter motor to pinion shaft. Six permanent magnets are used, eliminating potential field wire-to-frame shorts.

Nippondenso starter is a 4-field, 4-brush, 12-volt motor with a solenoid mounted within the housing. The unit has a 2-to-1 reduction gear set in a die cast aluminum housing. Starter has serviceable gear and clutch assembly only. If starter solenoid fails, entire starter motor must be replaced.

All models use a starter relay in starter circuit between the battery and starter solenoid terminal. Automatic Transmission (A/T) equipped vehicles use a neutral safety switch to provide ground path for the starter relay. Manual Transmission (M/T) equipped vehicles use a clutch pedal interlock switch to provide battery voltage from ignition switch to the starter relay. See Fig 1 .
