8.2 Liftgate does not Lower Down
1. Visually check the valves at cylinders for mechanical damage such as bent or broken valves.
2. Remove the cover at the hydraulic power unit and unplug the black cable (#2) with the inline fuse.
3. Unplug cable #6 from toggle switch to both the two wire release valve harnesses.
4. Connect female end #2 and male end #6 to energize release valves.
a. If gate lowers down :
- Check toggle switch harness and gray 3 wire harness for any damage.
b. If gate does not lower down:
- Check both release valves wires for any damage.
- Unscrew plugs of valves and stick a voltmeter into plugs and hit the down function.
Check each connection for voltage.
-If the voltmeter reads a voltage the cable is not damaged.
-If the voltmeter shows 0 volts, the cable is damaged.
c. Remove the plastic cap of the release valves – keep coil in place- hold a screwdriver close
to steel valve stem while pressing the down function on the toggle switch – if screwdriver
did not get magnetically pulled towards the valve, the coil is bad.
