FAULT
1. Unit leaks down over short
period of time.
2. Unit fails to reach limit of
extension or retraction or
binds at an angle near limit
of travel.
3. Unit operates slowly or
erratically during extend
or retract.
4. Does not run in either
direction.
3.0 TROUBLESHOOTING GUIDE
CAUSE
• Internal fluid bypass.
• Mechanical interference
with other components.
• Low supply voltage.
• Dead or low battery.
• Tripped circuit breaker.
• Tripped motor thermal
breaker.
• Faulty electrical
connection.
• Faulty relay.
• Mechanical interference
with other components.
SOLUTION
• Actuate Jackplate several times in
extend and retract direction.
• Check for interference between moving
components including: mounting fasteners,
steering system, loose parts, tools, etc.
• Check supply voltage. Voltage at
actuator leads must be between 10.5
and 14 V.
• Check supply voltage. Voltage at actuator
leads must be between 10.5 and 14 V.
• Check continuity across circuit breaker
near positive battery terminal. If the
breaker is manually-resettable, press
reset button. If the breaker does not
have a button, it will automatically reset
after it cools down.
• Allow motor to cool down to reset
automatically.
• Check for continuity in all harness wires
and connections in harness, including:
battery connection, circuit breaker,
harness wires, switch wires, switch wire
fuse. Check function of switch for
continuity. Replace faulty connections if
necessary.
• Check for correct function of relays on
harness. On activation of the switch in
either direction, there should be an
audible click in the relay and continuity
across relay lines when switching.
Replace faulty relay if necessary.
• Check for interference between moving
components including: mounting
fasteners, steering system, loose
parts, tools, etc.
