Hi can any one help me with a service manual for this 1990 Hyster E3.50XL serial number C098U01940L or at least the part cover the power steering as i dont have any. it has two EV controllers a EV200 and a EV100 i believe the EV200 is the traction side and the EV100 is the pump side which seems to control the power steering. The problem i have is the contactor doesnt energise and if i manually push the contactor in the power steer pump works but the steering is still hard to turn any help would be great as iv not work on these machines before....
