I need an electrical and hydraulic schematic for this machine. Also can anyone shed any light on how to get the back up alarm to work? Thank you in advance.

    Backup alarm is controlled via the Machine ECM AFAIK. Do you have any Diagnostic Codes.? Usually anything related to wiring or the alarm itself should generate something. Regarding schematics your S/N is wrong. It pops up as a 289D Series 3 skid loader.

    Your are correct the S/N should be any one of these 3 FJX 07459 FJX 11696 FJX 04447 No codes on any of the 3 machines

    Good job you gave all the Serial Numbers because there are breaks as far as the electrical schematic is concerned. One of your machines is in the range of 4000-6070, and the other two are in the range 6071-Up. I'll send you both.
