Does the machine sound like it is laboring at all? If the the aux is stuck on, normally the boom will raise but won't lower. Tilt normally won't do much of anything. That said some machines act differently. The low pressure light could easily be a sensor, I have never heard of low charge pressure make the functions act in a manner like that.

Try putting a jumper hose on the aux or if you have a continuish flow attachment like an auger and see if that makes any different. You are discribing text book aux stuck on. When aux is deadhead, it pushes the system over relief and that is what normally what happens.

Normally a very small piece of crap gets stuck in one of the stems. The stem is the piece the solenoid slides over. You can pull the stems out and try cleaning them out, but that never works for me. There are two of them, one for each direction. I never can remember which is which so I normally change the easier of the two, if that don't work, then I swap them. Try installing some sort of loop on the couplers first and see if it works normal, if this is the problem, it will.

I'm thinking U have a charge pressure issue. check out the operators manual,for that code. It kills the motor to protect the hyd/hydro's. Whats the code?
