Could be as simple as the coils put on wrong or connected to the wrong wiring. Up wiring connected to down, and down connected to up.The one outrigger that I can move retracts when I press extend, and extends when I press retract. I wonder if it's hydraulic lines were reversed at some point. As for the ground control PCB, that's the cpu board.
You’d need to loosen the holding valves too.This this is starting to drive me nuts. I need to get it out of my shop. Is there really no way to manually lift the outriggers besides cracking hydraulic lines?
One other curiosity I have found. I propped up the outrigger feet so that the switches are on, so the unit thinks they are down. When I switch it over to the basket controls, everything seems to work. The unit is in my shop, so I cant move it far, but it all moves. So I would assume that rules out the solenoid coils? It still flashes all the same codes.
