Hi my name is***** will be glad to help. Check the wiring and connector pins for the grapple switch and to the solenoid valve for that function. Test continuity in the switch and the circuit for any shorts or open circuits( broken wires/connections) causing the loss of that function. Verify power to the solenoid for the grapple function and if there is power there, check for a failed solenoid or problem in the control valve. Test all fuses and check the relays as well. Let me know the results and if we need to dig deeper into this.
