We've got voltage to the plug where it is supposed to be but the signal wire just reads a steady 10.5 volts. It never changes and the valve stays shut. We are running it with a Trimble FMX 1000. I've got my Trimble man on the hook but not sure when he'll have time to get here. Was just hoping maybe somebody could tell me what the voltage should be reading to move the valve from off to on and back the other way so I could test things in the mean time. Can't seem to find any good troubleshooting for my problem online and gave up being on hold with Raven. Thanks for any advice or direction to some good info online.
