Description & Operation: Notes

CAUTION: Disconnect negative battery cable before removing or installing any electrical unit or when a tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will help prevent personal injury and damage to vehicle. The ignition switch must also be in LOCK position unless otherwise noted.

Wound field starter motors have pole pieces. Arranged around armature, which are energized by wound field coils. Enclosed shift lever cranking motors have shift lever mechanism and solenoid plunger enclosed in drive housing, protecting them from exposure to dirt, icy conditions, and splashes. In basic circuit, solenoid windings are energized when switch is closed. Resulting plunger and shift lever movement causes pinion to engage engine flywheel ring gear, solenoid main contacts close. Cranking in takes place. When engine starts, pinion overrun protects armature from excessive speed until switch is opened' at which time return spring causes pinion to disengage. To prevent excessive overrun, switch should be released immediately after engine starts.
