Anyone have experience with this machine. I have a 2001 model with 6505 hrs and it wants to go into park mode off and on. Otherwise a great poor man 140H.

    A serial number would be handy to verify the correct schematics. Looks like the parking brake is spring applied and hydraulically released. Parking brake switch in the cab is controls a park brake solenoid that sends oil to the park brake to release it. How does the wiring to and from the parking brake switch look?
