Electrical operation of the control unit consists of four heavy duty solenoids, a thermal-switch located on the motor armature brush holder and a Low Voltage Interrupt (LVI) located in the control unit. The thermal-switch interrupts the power-in function and the LVI affects both the power-in and power-out functions and must be reset by allowing the charging circuit voltage to rise above 10 volts for more than 30 seconds. The thermal switch is reset only by allowing the winch motor to cool adequately (about 30 minutes). Solenoid number 1 and 3 control current flow through the field windings and solenoid number 2 and 4 supply current to the motor armature.
