Hi my name is***** will be glad to help. First check the oil level and condition for discoloration, burn smell, and metal/debris for any indication of an internal failure occurring. Also check the filter for fine metal or debris as well indicating a failure. If clean, verify pressures are in specs and if so check your fuses and relays and for your safety lockout switch/valve circuit. Let me know the serial number of your machine.
This machine is hydrostatic drive. check the hydraulic filters internally for fine metal that looks like metallic glitter that would indicate a pump or drive motor failure. If clean, raise the cab and check the pump drove coupler between the engine and pumps to be sure it has not failed and is turning the pumps. Let me know the results and if we need to dig deeper.
Pleasure to help. I am having trouble accessing the Case construction parts site today for some reason but you can access your parts breakdowns online if you did not know through cases site. For your relays its fastes to swap a known good one out with the others one at a time. Are you getting any error or fault indicators on the display?
What fault codes are you getting?
Thanks for the information... I would test all your fuses for power on both sides with the IGN switch on as well as swapping your relays with a known good one for test purposes. If ok be sure the oil and filter are clear of metal/debris indicating internal problems. If ok then you likely have an ECU or power/ground/communication and software problem with the ECU. The dealer laptop will likely be required to verify and check the parameters and re-calibrate and reflash the system software if needed. Let me know
