Austin....I watched your video and much better understand what's happening. Do you have the Owner's Manual? My system is semi-automatic and may differ from yours somewhat. And Lord knows I am no hydraulic technician. But, again, it sure seems like your pump reaches a point where it can no longer build enough pressure, hits a wall...and shuts off when it overheats. Just a guess. In my OManual, there is a good diagram of the Jack Valve Assembly and its 3 jack leg solenoids. There is also a very good wiring diagram. My system includes 3 leg solenoids and a dump valve solenoid. I believe the 3 leg solenoids control fluid to the jacks....and I surmise the dump valve solenoid would control fluid back to the reservoir when raising the jacks. It may be that the dump solenoid is hanging up somehow.
The "trouble shooting" part of my manual lists these possible causes for "Jack Will Not Extend, Pump Is Running" - 1) Fluid level low, 2) Pump harness fuse blown, 3) Dump valve solenoid faulty, 4) Valve solenoids miswired, 5) Other (contact Power Gear).
The thread on this forum that I referred to re the solenoids, with pics, is Things Go Thump in the Night....I believe. Perhaps it would help you in some way. If it were me, I would talk to the P/Gear folks (IF you can get a hold of them) and ask about the dump solenoid. Also, has anyone worked back there in the vicinity of the pump and wiring area that may have dislodged a wire or 2 and perhaps did not rehook them properly?
Good luck, and please let us know what you find out! Thanks....Heap
