first i would like to say hi and thank you for your time, im new here but a long time raymond field technician. im hoping someone could help me out.

has anyone came across an order picker that wont steer while travel is requested? it steers just fine and travels fine but wont do both at the same time. here is what i found so far: only 7 to 14 volts at the steer motor, the orderpicker is seeing the request and processing it because as soon as the travel pot is returned to neutral the drive unit will go to where it was requested while traveling????

the tech before me has literately changed everything before i was sent out on it trying to fix a g3 code. steer card, t.m's, tractor manager, otm cables, power card, firmware, steer motor, steer encoder and cable, probably the filter card, i think the carriage control card is old.

i have ran every test that has anything to do with steering in anyway, all pass. battery is good, no short the frame or voltage leaks to the case. IM STUMPED.. field service mentioned to me via phone call that the vfc's and carriage control cards are being manufactured differently or from another suppler,and unless i find an old style card. this truck cannot be fixed...

has anyone else heard about this, or had this symptom before?
