Hydro issues

[Fixxit]

I am working on a Thomas skid steer, I found a bad seat belt switch and replaced it , the 2 coils on the hydro valves lit up and it worked ( the lift arms and bucket) after it warmed up the coils are still lit but no lift or tilt ?? I noticed that the coils are located on the end of the hydro valves where the spring/detent are located , is there a mechanical part that could be stuck? I can get the arms to go up slowly, pushing up or down ?? Thanks Daniel

Try removing the coils to see if there is a pin sticking out that locks into the valve spool to creat a safety lock. You could have a bad coil that drops the lock pin whenit gets too warm.
Just my guess....
