when you say no hydraulic operation do you mean for ALL functions? any lever pulled does not work?
what happens if you manually press the hydraulic contactor? the motor should run.
serial number of truck ???
if contactor is good then I am missing something ,how is does your measured 36v drive signal not energize it , verify that this is a viable coil drive signal signal, if it passes a bench test with 36v manually injected then the driver voltage measured at machine outputs are not viable
already took out contactor and checked.
contactor is good.
if the hyd contact is recieving a drive signal (measured at both coil signal terminals) then it would appear that your coil is open or solenoid is binding , check coil continuity or isolate terminals and inject signal.
steer, drive and hydraulic contactors all have 36v.
but hyd contactor not closing.
if it is a card problem, which card (drive, logic or bridge card) is most likely defective?
no code showing, can't decide what procedure to check.
how is the bsoc, is there signal voltage driveing hyd contact?
