TROUBLESHOOTING

HOW TO KNOW POINTS TO CHECK

Poor connections. Recheck wiring with the owner's manual.

HI/LOW voltage tester does not work. Connect it on battery posts (+ and -) of a functional battery.

If there is no light, the tester is damaged.

The control switch inoperative. Test both connectors with HI/LOW voltage tester.

If light comes ON in both positions (IN & OUT), the switch is

operative.

Relay is damaged When it is working, there is a "CLICK" sound when the control switch

is activated. Check connections with HI / LOW voltage tester.

Winch is damaged The ultimate test is to connect the winch directly to the battery and

reverse the wires to test both directions. If the winch doesn't work, it is

damaged.

The limit switch is damaged. When the limit switch is pushed or stuck inside, the winch can't raise

the accessory, only lower it. If not replace it.

The breaker is damaged. Check the voltage on both terminals on the breaker with the HI / LOW

voltage tester. If not replace.
