i need an xpert, my tilt werked going up, but now will not go down, what do i check first? i am getting a power reading at the switch. but i'm lost from there.
A simple test would be to allow it to drop down slightly manually by opening vent screw on the pump. Then see if it works again. If it does...you ram has stuck on its upper position.
If not. Relay is suspect. Change the down one over for the up one and see if you have the reverse.
