All,

Pretty stumped on this current issue. The walkie pallet jack moves forward and back fine. Hydraulics seems to malfunction periodically. Sometimes it will lift and other times it won't. No error codes are displayed and I have already replaced with a new lift solenoid. I've checked the hydraulic fluid levels and it seems to be fine. I've also swapped the handle with another one from a working pallet jack and continue to have the issue. Could it be a problem with the hydraulic pump? Are there any additional areas i need to check for wire shorts? Any help is greatly appreciated.
