5) GATE IS NOT LIFTING UP
a) Check resettable Circuit Breaker on top of battery
Push Reset Tab back in, if popped out.
b) Check fuse on top of battery (qty 1) and
at circuit board (qty 2) inside pump and motor box at mount frame
c) Start van and run engine in fast idle for charging the battery
if liftgate start working, recharge battery
test battery and replace if necessary
d) Check power on board between J-11 #4 and J-2 #(-) with voltmeter while pushing lift up buttons
(above 10 volt is necessary for proper use of liftgate)
less than 10V; Jump #2 to #4
on J-11
voltage jumps more than 1 volt, call Palfinger for assistance
****DO NOT LEAVE JUMPER ON J-11
– GATE MUST BE SHUT OFF WHEN NOT IN USE****
5.1) Check Battery Power
a) Unplug J-3(foot control), J-41(B-13, B16,
jump J-11 #4 to J-41 #GN
) and J-31(Hand control)
Keep the 3 connectors unplugged (gate also operates without plugs connected)
b) Unplug J-1 (Main power), wait 10 seconds and plug J-1 back to the board (Reset the board)
c) Plug each connector back - one at a time - and check functions of gate after plugging in each.
5.3) Check for short in optional equipment
a) Check for voltage at J-1 #3 to Ground J-2 #(-) to engage motor solenoid while pushing lift knobs
b) Check for voltage at small motor solenoid terminals to Ground J-2 #(-) while pushing knobs and
listen for clicking of the motor solenoid
– no voltage or clicking
check wire to motor solenoid
c) Check voltage across the small motor solenoid terminals with test light while pushing knobs
See a light
power is reaching solenoid
d) Check for main power at the large solenoid studs, one has voltage; if not check connections to battery
e) Check both big solenoid studs for voltage while pushing the opening knobs
if not
solenoid is bad
f) Jump large terminals at motor solenoid
- If motor runs
motor solenoid is bad
- If motor does not run
Bad motor or bad ground
- Tap on motor
motor starts running
– bad brushes
5.4) Check motor solenoid power to run the motor
a) Check voltage at J30 #4 to Ground J-2 #(-) for power supply of the control buttons
b) Check voltage at J30 #5(lift) to Ground J-2 #(-) for lifting signal
Signal on J30 #5
control buttons are ok; if no signal - check for damaged wire or loose cables
to control buttons or damaged buttons
5.2) Check function of control buttons(J30) and hand control(J31)
