Winch Roller Fairlead (Option)
Replacement
The winch roller fairlead provides greater functional versatil-
ity. The winch cable can be routed at much sharper angles
since the fairlead rollers will keep it from binding on the
bumper edges.

during removal.
1.
Remove the cotter pin, hook retainer pin and hook from
the winch cable.
2.
Remove washers, bolts, and the roller fairlead from the

NOTE:
Individual parts may not be available for some of the
following repair procedures. Assemblies must be used in place
of individual parts. Check for parts availability before disas-
sembly.
Winch Troubleshooting
Winch Inoperative
1.
Check for jammed winch cable.
2.
Check winch control cable connector for corrosion or
loose connection. Clean corroded connector or secure
loose connection.
3.
Check for loose or damaged winch power cables. Using
voltmeter, connect positive meter lead to positive power
cable (red) at the winch motor, and negative meter lead to
the winch motor ground cables (black). If voltage is not
present, repair or replace winch power cables.
4.
Disconnect winch control from winch. Using an
ohmmeter, check for continuity between the common
terminal and the other two terminals on winch control
cable connector. Check for continuity one at a time, while
holding control in the OUT position and the IN position. If
continuity is present in both positions, repair winch. If
continuity is not present in both positions, replace winch
control.
