Thanks for the suggestions. We ended up just manually opening the on off valve and disconnected the mechanism so it couldn't shut off. Was able to run for a little while today. The flow control valve will shut the system clear off when we stop. It does take it a few seconds to open all the way up, so I don't like that it takes a bit to be putting on the full rate. Still waiting on my Trimble man so we'll see what happens there. I'm pretty sure since I never see a change in voltage to the valve that the signaling electronics are malfunctioning. But I'll have to admit that I'm a little out of my league on the diagnosis here.
