DELCO-REMY Starter Controls: Description

Solenoid switch consists basically of two windings mounted around a hollow cylinder containing a movable core or plunger, a shift lever is connected to plunger. Push rod and contact disc are assembled in line with plunger. When windings are energized, plunger movement by means of shift lever moves motor drive into mesh with ring gear and contact disc is pushed into firm contact with solenoid battery (B or BAT) and motor (M or MOT) terminals. With motor windings connected directly to battery, cranking takes place. Two windings in solenoid are hold-in winding and pull-in winding. Drive end housing of starter is extended to enclose entire shift lever mechanism for protection from dirt, splash, and icing. Solenoid is flange mounted on drive end housing and is sealed to housing with sealing compound. Shift lever return spring is compression type and is located inside solenoid case.
