I have a 2000 763 that stopped lifting this past weekend. Everything else works. When the seat bar is down, all lights indicate that all systems are go. The pedal that controls the lift feels like its locked though. It used to do this intermittently before and I would just disconnect and reconnect what I suspect is a solenoid, and it would start working again, but now its just locked. The connector I would disconnect comes from a switch/button that I can imagine activates the lift. Any ideas? Thanks, Guillermo
