Skidsteer worked fine about 3 months ago. Started up 2 weeks ago to move it and the bucks and arms move fine but it will not move forward or backwards. Added about 4 gallons of oil to the hydraulic tank. Does not seem to be putting a load on the engine at all when you move the joysticks. Had 14 volts at the solenoid on top of the pump with red wire. The orange wire seems to be a neutral that allow flow to go back somewhere. How would I know if charge pump could have gone out? Do auxiliary pump still work if charge pump is out. Could it be air trapped in system due to it being low?
