runs fine if you are just moving tracks but you cant run just one track it will kill engine. swing and bucket and boom will try to or sometimes kill engine. 6 line going to track control. If I take the 2 off that go to the hydraulic lock valve and loop them together and start engine I get hydraulic fluid coming out the fool control valve . Should that happen I am wondering if main valve body needs rebuilt maybe a valve in there is stuck? Or should I be looking for something else?

Found the issue Kind of. two solenoids on top of the hydraulic pump. Shot power and ground to one closest to access door and engine took off and ran fine. so I played with one and no engine change. I wired them both to constant power and went to operate and found hydraulics operated at creep speed. unplugged them both and briefly hot wired the one closed to engine and hydraulics came back but then engine bogged again so i briefly hot wired the one furthest from engine and engine speed came back. I left them both unplugged for now but havent had a chance to test it digging yet..
What do those solenoids do and is there a way I should wire them?
Since all computers are unhooked Im thinking about a couple toggle switches in the cab.
original wires going to these solenoids have no power or ground with key on or engine running.
