Cat Lift Trucks (& Caterpillar) NR3000:

Can someone out there shed some light on this one...."The high side switch that drives positive to valves is opened when it should be closed" ??

check your wiring harneses on the reach pentagraph for open circuits, especially around where the wires run down the carriage to the solenoid manifold block at the bottom of the carriage.
Also the wire harness in the mast has been known to get open wires and will cause this error.

check it out and let us know what you find
