is the reach working is power steering working? if so the aux motor and pump is ok. as i said before i believe you have bad wiring. there is a small cable (#18/4) that runs through the reach assebly and provides power/ground for the solenoids behind the load backrest, these solenoids are for tilt/sideshift. the cable is bent up/down constantly as you reach and retract the forks causing it to wear and break frequently. check this cable!
