Control Unit, Winch: Operation

In the power-out mode, solenoid number 2 and 3 are energized by the remote control switch. Current flows from the positive battery terminal through solenoid number 3 then through the black motor cable to the number 2 and number 1 field windings. From the black motor cable current then flows through solenoid number 2 to the motor armature to ground.

In power-in mode, solenoid number 1 and 4 are energized. Current again flows from the battery positive cable, but this time current flows through solenoid number 1 then through field winding number 1. Current flowing in the reverse direction through the field windings cause the motor to turn in the opposite direction. From the red motor cable current then flows through solenoid number 4 to the black cable going to the motor armature to ground.
