I have a 2007 cat 257b2 parking brake won’t release. Everything else works fine . There is no power being delivered to the parking brake solenoid. Push parking brake release button light goes out but machine won’t move. I have battery power jumped straight to the parking brake solenoid for now just so I can use the machine, and it works fine, but I’d like to fix the problem, hoping someone else has had this issue and can save me a few hours of trouble shooting, this not having a electrical diagram kinda sucks
And unless you give a machine Serial Number you’re not likely to get one, at least not the correct one. “2007 cat 257b2” is unfortunately not sufficient information to go on.
