MOTOR
DESCRIPTION
The winch is driven on one end by a two direction
electric motor powered by the vehicle electrical sys-
tem. The motor is internally protected by a thermal
switch that is activated when the motor gets too hot to
operate efficiently.
Winch motor controls consist of a relay pack mounted
to the motor, and a remote control connected to the
relay pack with a cord. The winch power source
cables are connected to the relay pack which in turn
feeds power to the winch motor through electrical
cable connections. The main function of the relay pack
is to allow the operator to switch the winch on and off
in both directions. The winch relay pack also includes
a Low Voltage Interrupt (LVI) used to prevent winch
operation in the event of battery power dropping below
10 volts.

RELAY PACK
DESCRIPTION
Electrical operation of the control assembly consists of four heavy duty relays, a thermal-switch located on the motor
armature brush holder and a Low Voltage Interrupt (LVI) located in the control assembly. The thermal-switch inter-
rupts 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). Relay number 1 and 3 control current flow
through the field windings and relay number 2 and 4 supply current to the motor armature.
Operation
In the power-out mode, relay number 2 and 3 are energized by the remote control switch. Current flows from the
positive battery terminal through relay 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.

INSTALLATION
WARNING: Always keep hands and clothing clear
of the wire rope, hook and fairlead opening during
operation and when spooling. Failure to follow
these instructions may result in personal injury or
death.
CAUTION: Wire rope must spool on the winch
drum in the direction indicated.
1. Feed the new wire rope end (3) through the guide
rollers.
2. Attach the flat side of the wire rope end (3) to the
winch drum (1), apply red thread locker to the
threads and install the bolt (2).
3. Wrap the wire rope around the spool approximately
one time, in the direction indicated on the spool.
4. Tighten the bolt to 3 Nꞏm (25 in. lbs.).
5. Arrange the wire rope so it will not kink or tangle
when spooled.
6. Lock the winch drum by rotating the clutch lever (2)
on the winch to “Engage.”
NOTE: Always make sure the clutch is engaged or
disengaged fully.
7. Connect the remote control to the socket.
8. Install the hook (5), the pin (1) and clip (2) to the
end of the wire rope (4).
9. Keep the rope under light tension and spool the
rope back onto the winch drum in even layers.
10. Stop frequently to tighten and straighten the lay-
ers as necessary.
11. Repeat this process until the winch hook (5) is the
same distance from the winch as the full length of
theremotecontrol.
12. Using the hook strap, walk the wire rope towards
the guide rollers, carefully spooling in the remain-
ing wire rope by pulsing the remote control switch.
NOTE: If you do not have the hook strap, use a
length of cord or similar when handling the hook during servicing of the winch.
13. Store the winch hook on the most outboard loop of the tow hook and remove the slack from the wire rope.
