TOM/MN - 3/11/2016 06:44 I had the same problem with one boom not getting enough pressure. Turned out to be a bad spade connector. Not getting enough voltage to that solenoid. New connector and all is well. But would have to agree with the other posters that they can be a pain to keep opening properly.
How much is a ball valve setup on a three valve boom?
You've have at least $500 into a 3 ball valve system, plus some extra fittings. (Note: this style uses 3 wires = one ground; one Constantly HOT with 12 volts; one Switch wire (for On/OFF function)
