Problem Probable Cause Corrective Action
Jacks will not extend to ground,
pump is running.
Little or no fluid in reservoir Fill reservoir with DEXRON III
Leg valve is inoperative Clean, repair or replace
Electronic signal is lost between
switch
Trace wires for voltage drop or loss
of signal and leg valves. Repair or
replace necessary wires or replace
switch.
Any one or two jacks will not retract.
Hose damaged or disconnected.
Replace with new hose or reconnect
hose.
Return valve inoperative. Replace inoperative return valve.
Electronic signal is lost between
switch and solenoid.
Attempt to retract jacks in MANUAL
mode. If successful, replace control
pad. If not, test for voltage drop
between switch and leg valve.
Repair bad wiring or replace
defective board or valve.
Troubleshooting – Power Unit
Before attempting to troubleshoot the Power Unit, make sure an adequate power source is available. The unit
batteries should be fully charged or the unit should be plugged into to A/C service with batteries installed. Do not
attempt to troubleshoot the Power Unit without assuring a full 12VDC charge.
The following tests require only a DC voltmeter (or DC test light) and a jumper lead.
1. Attach voltmeter (or test light) leads to the negative and positive terminals on motor solenoid. Does
the meter indicate 12VDC? If YES, see Step 2; if NO see Step 3.
2. If YES, at the motor, activate system, check the incoming leads to 12VDC (if necessary, disconnect leads
at wire splices). Does meter indicate 12VDC? If YES, Power Unit needs to be replaced. The motor is
not field serviceable. DO NOT ATTEMPT TO REPAIR. If NO, Inspect all wires and connections between
the motor solenoid and the motor. Repair connections or replace motor solenoid as necessary.
Recheck as in Step 1.
3. If NO, Inspect all connections between battery and motor solenoid. Inspect Manual-reset Circuit
Breaker in battery feed line. Recheck as above in Step 1.
Since there are no field serviceable parts in the motor of the Power Unit, electrical troubleshooting and service is
limited to replacing only those components as previously outlined.
Thorough inspection of wiring and connections is the only other electrical service that can be performed.
