Hi,
Im having a problem with the reacch tilt and side shift on an EASI-R30TT The auxiluaries will only move a short distance when operated approx 3 inches the the switches have to be released and pressed again.
Hydraulic pressure in aux lines falls below 120lbs,
I can here the solenoid valves operate onreach tilt and side shift, and the pump is running.
have checked the header cable for continuity and it was ok,
Have checked all solenoids and valves on main lift and aux valve block by substitution by swopping of known good truck and they have proved to be ok
Im beginning to think this is not a hyd problem but a card failure.
Has anybody got some idea were I should be looking for this problem.

Regards titus
