Troubleshooting
Fuse
The Power Tongue Jack is provided with a 30A ATO-type
in-line fuse and will need to be replaced if it blows. The
battery must be fully charged prior to operating the Power
Tongue Jack. Low voltage from the battery will cause the
fuse to blow prematurely.
NOTE: The “On” and “Off” light switch (Fig.6A) controls the
Power Tongue Jack’s light only. If left on for an extended
period of time, the light will drain the trailer’s battery.
Clutch
The Power Tongue Jack is provided with a clutch and a
motor. The clutch will slip under two conditions:
A. The Power Tongue Jack has reached its extend or
retract limit.
B. The tongue weight of the trailer has exceeded the
capacity limits of the Power Tongue Jack. Items stored in
the trailer can vastly influence the weight on the Power
Tongue Jack. Reorganize stored items if the Power
Tongue Jack motor clutch continues to slip.
NOTE: Release the switch immediately when the clutch
noise occurs. The clutch is the overload protection for the
motor. The clutch should not slip during normal operation.
This will cause excessive wear on the clutch and the motor.
