Pulled the steering unit and it is an Eaton Charlynn unit # 211 1013 001 which in an open center unit.  Say's it's a Non-load reaction.  When I pulled it out I ran a union fitting between the pressure and return.  That go rid of the constant pressure at the steering relief and main.  Everything works the way it should now.  When you actuate a remote the main pressure goes up to relief pressure, from near zero, whereas before there was always pressure reguardless of anything being used or not.  Put shop air to the pressure port on the steering unit and it does flow through back out the tank port.  Is there something that could be causing it to close when hydraulic pressure is applied?
