Serial # NPR345-0203-9700....Has an intermittant problem where none of the hydraulics will respond,no lift or lower...no reach tilt or sideshift...after talking with another tech in the company that i work for he said there is possibly a broken wire in the pantograph between the two control/solenoid blocks,he says that the solenoid card sends out a refrence voltage to them and if it isnt seen coming back then the hydraulics wont work. Guess he has found this on a few occacions.

the solenoid card is new a few months ago as are the control handle switch's for lift/lower and reach/tilt sideshift push buttons.

I want to see what the consences is on this issue before i start tearing wires out of the pantograph(which is a double reach pantograph)
