The lift switch may also fail in an open condition. If this happens the lift will not operate in one
direction. Perform the following steps to determine if the switch is open. If the lift moves in one
direction but not the other, replace the lower control module.
3. If the lift
does not move in either direction or fails to move in the “UP” direction (more torque is
needed to move the lift in the “UP” direction), the battery could be at fault. Measure the voltage on
the battery, and if it is 11 VDC or lower replace it.
If the battery needs to be replaced, make sure that the 14.5 VDC battery charging supply is putting
out 14.5 VDC. If the 14.5 VDC charger voltage is not present on the lower control module, replace
the lower control module.
If the lift moves “DOWN” but will not move “UP” (or has trouble moving up), monitor the battery
voltage while commanding the lift to move “UP”. If the battery starts out at 12VDC, but drops to a
significantly lower voltage when commanded to move “UP”, replace the battery.
4. If the lift will not move in either direction, ohm out the cable that goes from the lower control
module to the lift motor. If there are opens in the cable, repair or replace the cable.
