Repair and Diagnosis: Electrical: Starter: Starters: Description

The starter motor consists of 4 parallel fields, 4 brushes and a solenoid shifted, overrunning clutch. A 1.5 HP model is used on 225" (except LeBaron and Diplomat) and 318" engines. It has a gear reduction of 3.5-1. A 1.8 HP model is used on all other engines and has a 2.0-1 gear reduction.

The 2 motors appear identical, but have external and internal differences. The field frame and armature are larger on the 1.8 HP motor.

Both motors have a shock absorber clutch drive unit, which absorbs the initial shock of cranking and protects the clutch unit from engine backfires during cranking.

The starter system consists of 2 separate circuits, the supply circuit which provides the heavy current to the motor and the control circuit which actuates the solenoid. Unless otherwise noted, service and testing procedures are the same for both motors.
