TROUBLESHOOTING

2. Find out if vehicle is equipped with optional battery box, truck charge line, tractor charge

line, or trailer charge line. Check optional battery box cables and charge line cables for

damage, dirty connections and loose connections. Replace damaged battery cables,

clean dirty connections, and tighten loose connections.

3. Check if vehicle batteries and optional battery box batteries are fully charged. If

required, fully charge batteries with a battery charger. Replace batteries that cannot

be fully charged. If battery charger fully charges batteries, use vehicle manufacturer’s

speciﬁ cations to check the vehicle battery charging system. Do not operate Liftgate if

vehicle charging system needs repair.

1. Check for 12.6 volts dc input to motor solenoid by using voltmeter between terminal A

(FIGS. 49-1 and 49-2) and ground. If there is no power to the motor solenoid, make sure

pump box master disconnect switch is ON and circuit breaker is set.

4. Use a 6” long, 10 gauge insulated wire as a jumper to connect pump motor solenoid

terminal A and terminal C. Check for 12.6 volts dc output from motor solenoid by using

voltmeter between terminal B (FIGS. 51-1 and 51-2) and ground. If a low voltage or

0 volts is indicated on terminal B, replace motor solenoid. Also, check electrical load

cable for damage, dirty connections, and loose connections. Replace cable if damaged,

clean dirty connections, and tighten loose connections. Use multimeter and applicable

schematics in this manual to check switch controls and interconnecting wiring.

NOTE: For dual pump system, check secondary pump and motor ﬁ rst.
