6. Check for oil leakage around the power pack and Use only original spare parts. If in doubt contact your inside mount tube. Tighten or replace components if PALFINGER Liftgates distributor or call PALFINGER needed. If you perform work on any hydraulic Liftgates directly. - Page 28 Power Cable to Solenoid Coil Test Check for broken power wire in solenoid cable: • Unplug connector at valve. • Set multimeter to read DC voltage. • Put positive lead of multimeter in plug. • Put negative lead of multimeter in other hole of plug.
- Page 29 Solenoid Coil Test If one or both release valves on lift cylinders are not opening up, low voltage may be the cause. A minimum of 9V is necessary to properly energize each of the solenoid coils. If the minimum voltage is present at both coils, the coil may not be generating the magnetism needed to open the solenoid valve.
