I bought this machine and was told the hydraulic pump had went on it,the bucket functions worked but no tracks,,just grinding. Starts and runs great.I had the hydraulic pump rebuilt and drive motors tested then reinstalled myself.went to try and it does the same thing but no grinding. It feels like the parking brake is still on. I replaced brake selonoid and still nothing. I have done all the seat belt and seat sensor trouble shooting, checked wires all down to selonoid, checked all the fuses and visually inspected all wiring I could see. Park brake symbol goes out on monitor, but switch remains lit, I'm not sure if that's normal?. Also the codes its showing are F9P8(park brake output short) and F985(hydraulic oil temp low), neither of these I know how to check anymore. Anyone else had this problem? Is there something I'm missing?!

The switch does remain lit (that is normal) could be the brake solenoid or a wire going to it.

Yea I traced the wire all the way back and looks good, also put a new selonoid valve on, voltage down at the valve and I can hear it clicking off. The only thing I can think of left that could stop the hydraulic oil would be the 2 speed valve maybe faulty?

Still no luck if anyone has any advice! Thanks!
