Having problem with my E-47. It will only angle left when I go to angle right it goes left, angle left goes left. Up and down are fine. Replaced cross-over valve, replaced couplers, getting power to c-solenoid,replaced c-solenoid coil and all getting magnatism to the c-solenoid, took whole pump apart and cleaned the s--t out of it. Took different pump off one of my other trucks and it works fine with that one. At my wits end. Anybody????????
