Check your safety interlock switches and wiring. Also check your joystick controller's and wiring harness for any damage or open circuits. Verify continuity and resistance through your wiring harness and connector pins to be sure everything is intact and checks out okay. Check all of your fuses and relays. If this all checks good, you may have a software related issue within the machine controller requiring a software update or reflash reset everything back to factory settings as well as a recalibration of all your controls to the machine controller. It's a pleasure to help anyway I can.

Ok checked all that seems ok.before this happened we change ahose on the right side motor which run next to some wire going to that motor do you think some of the wire going to that motor could be our problem
Mechanic: Dan, Technician replied 3 years ago
Pump Forward Control Solenoid. If you've already replaced the solenoid, that leaves either a problem in the wiring harness with the wiring or connector pins, or a problem with the machine controller possibly. I would take it closer look at that circuit and test out the circuit with an ohmmeter for resistance and continuity to be sure that the wiring checks out good.
