Both windings are energized when the ignition switch is tumed to the start position. When the plunger disc makes contact with this solenoid terminal, the pull-in Winding is deactivated. At the same time, the plunger contact disc makes the motor feed connection between the battery and the starting motor, directing current to the field coils and starter motor armature for cranking power. As the solenoid plunger moves, the shift forla also pivots on the pivot pin and pushes the starter drive pinion
