OK, I have replaced both main harnesses that go from the cab to the engine and hydraulics. Everything worked (still sluggish) when we left. Today, the engine fires up, but no hydraulics (this machine is driving me nuts). The only item I could think of is the safety switch under the handle which is bypassed (waiting for a replacement switch). It was still bypassed. I have no hydraulic functions at all. The only think different was the switch behind the seat (release or KPSS) was switched when we put the seat back in place. Can anybody give me help on what to look at? I do not have any errors showing on the display. Thanks for the help!!!!
