Troubleshooting
SECTION 2 : INSTALLER
PROBLEM
Lift does not operate or lift operates slowly or
intermittently
CAUSE
Bad electrical connection(s) / Circuit breaker
SOLUTION
Check / clean all connections that might be
loose or dirty. This is the #1 cause of a poorly
performing lift. The lift motor requires quality
electrical connections to operate at full
capacity; any break in the wiring will slow down
the motor and it will deteriorate prematurely.
Inspect the full length of the wire harness
to ensure the insulation is not torn. The lift’s
vehicle power harness running through or
under the vehicle is subject to road debris and
rubbing against the vehicle’s frame which can
cause a short.
Verify the circuit breaker. The circuit breaker is
located about 6” from the connections to the
vehicle’s battery. The breaker will self-reset if
overloaded; however, verify (with Ohm meter
or test light) that the breaker is functioning.
[Figure 28-1] Or replace it with a new/known-
good circuit breaker and perform the following
tests. [Figure 28-2]
