Looking for help with 1999 JD 250 skid steer. The parking brake won't release, this locks out the drive and bucket hydraulics. Have tested and by passed the seat switch and the seat belt switch, replaced the park brake switch, still no movement. Was told the instrument cluster has a module that fails at times. My question is anyone have experience with these that has by passed the module for test purposes. I have the wiring diagram, but no diagnostic charts for module.
