TROUBLESHOOTING
DEALER ONLY SECTION
The following procedures are reserved for the approved
installer/dealer. They should not be attempted by
anyone without proper knowledge of automotive
electrical circuitry.
Be careful when troubleshooting with voltage meter.
The instruments will detect voltage but may not indicate
a tear or poor connection in the wiring.
It may give a false indication since it will only indicate
that there is some wire connection –not necessarily
enough.
[Figure
27
-2]
It is strongly recommended that you examine both
voltage and current, or isolate sections of the lift wiring
using process of elimination with a known good/fully
charged 12V automotive battery or known good/fully
charged power chair/scooter battery.
PROBLEM
• Lift does not operate.
• Lift operates slowly or intermittently
CAUSE
Bad electrical connection(s) / Circuit
breaker
SOLUTION
Check / clean all connections that
might be loose or dirty. 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.
CAUTION!
Be careful when troubleshooting
with a test light or voltage meter.
They may give false indications.
Figure

-2
Inspect the full length of the wiring 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. Or replace it with a new/known-good
circuit breaker and perform the following tests.
