Section 8: Troubleshooting
Lift does not operate
• Check the power supply. The wiring harness red wire and the ground must be run directly to the
battery.
• Run the lift from a shop battery and not through the vehicle wiring harness. If this solves the prob-
lem, check the vehicle wiring harness for bad connections or broken wires.
• Check wiring harness fuse. Replace if necessary with a 25A breaker.
Motor does not lift the platform completely when in use
Check the lift harness ground wire and make sure it is connected to the battery. A poor ground will
cause the motor to run slowly and have less lifting capacity.
Motor works intermittently
• Check wires leading to the toggle switch of the motor housing box and the toggle switch.
• Check lift ground wire and make sure it makes solid contact with the vehicle frame.
• Check vehicle battery.
Platform does not fold properly when not in use
• Make sure the lift arms are in the down position
• Make sure there are no obstructions in the pivot area of the platform
• Check the lift platform springs for wear or damage
License plate light does not work
Make sure the Flat 4 trailer plug on the vehicle wiring harness is properly attached to the trailer light
plug on the vehicle.
What do I do with the extra length of wire from the wiring harness?
Coil the excess wire and zip-tie it to the vehicle frame out of the way of moving parts. Be sure the
excess wiring is in a location where it cannot be snagged by road debris, and that it’s a safe distance
away from the vehicle exhaust. Do not cut the excess wiring.
Lift does not reach the ground when lowered completely
Check that the hitch adapter is installed at the proper height. See page 4 of these instructions.
Lift bottoms out when traveling over bumps and driveways
• Always traverse steep inclines, speed bumps, or uneven surfaces slowly and at an angle to pre-
vent dragging or scraping the lift on the ground.
• Check that the hitch adapter is installed at the proper height. See page 4 of these instructions.
