COMPONENT LOCATION

OVERVIEW

The 9.5XP winch is manufactured by WARN in the U.S.A. The winch features a 6 Horse Power (HP) High Output Parallel Series Wound winch motor.

The winch has 3-stage planetary gearing and full-face contact drum seals, motor and end housing gaskets for extreme duty water resistance.

OPERATION

WARNINGObserve all Warnings and Cautions detailed in the WARN Winch Operator's Guide and the WARN Basic Guide to Winching Techniques before and during winch operation.

The winch motor is powered by the vehicle battery. The motor provides rotational power to the gear mechanism, which in turn rotates the winch drum and winds the cable.

A remote control is used to operate the winch. The remote lead plugs into a remote control connector which is connected to the control box and allows the operator to control the winch winding direction while standing at a safe distance from the wire rope.

The clutch allows rope to be pulled off the drum without motor operation. Refer to the WARN Basic Guide to Winching Techniques.

The winch is mounted on a bracket which is attached to the vehicle chassis frame. Two additional brackets are attached to the front bumper armature mounting plates. The brackets allow the attachment of the winch mounting bracket. The winch is secured to the bracket with four bolts, washers and nuts.

The winch control box is located on the rear of the front bumper armature. Two additional holes are drilled in the armature and the control box is attached with two bolts, washers and nuts.

The winch control box manages the power supplies to the winch motor and also receives the input from the remote control for winch operation. A remote control socket is located at the LH (left-hand) end of the winch mounting bracket and allows for the connection of the remote control.

The winch will operate with the ignition on and the engine not running, but this is not recommended due to excessive battery drain. Therefore it is recommended that the engine is running at all times when the winch is in operation.

A blue wire from the winch remote control socket is routed via a joint below the EJB (engine junction box), through the vehicle bulkhead grommet behind the EJB. The blue wire is then routed behind the glove compartment and along the floor console to connector C0253-12 on LR3 vehicles (up to VIN 513325) and C2754S-13 on LR4 vehicles (from VIN 513326), which is located below the cup holder, behind the transmission selector lever. The wire is spliced into the green/white wire into the connector. This connection on the blue wire provides an ignition on signal to the winch control box when the remote control is plugged in.

A red cable is attached from the battery positive (+) terminal to the positive terminal on the winch power interrupt solenoid. This connection is the main power supply to the winch power interrupt solenoid for the winch motor and control box. The winch power interrupt solenoid is located on the plenum in the driver's side of the engine compartment.

A white wire from the winch remote control socket is connected to the winch power interrupt solenoid and energizes the solenoid relay when the ignition on signal is received. A large red wire from the winch power interrupt solenoid is routed to the winch control box. Power is not supplied to the winch control box until the remote control is connected to the remote control socket and the ignition is on.
