Once more thing I can think of did you prime the system before you installed the check valve. If you don't it will never clear the air out of the pumps head and will not spray. Once you have flow from the out side of the pump then it's good to go. |
I am fairly certain I have narrowed the problem down to the controller being faulty. I disconnected the green wire from the map and tapped it to the gray 5v wire as you instructed. The only lights that came on brightly were the yellow and the red LED. The green LED was only very dimly lit and would go off after a second. Sometimes the yellow LED would continuously flash after doing the test. During the test, the disconnected water line would not flow any water. (The line was disconnected at a point before the solenoid... so the water line was only connected to the pump.)
To make sure that I had no wiring issues from the pump to the controller, I spliced a new wire into the pumps power wire (at a point near the controller). I took the new wire and tapped it to the positive battery terminal to see if the pump would work right from a direct 12v source. This test was successful, and the pump fully primed the line with water. I re-tested the controller via the 5v gray wire as I previously did with the same failure. Only the red and yellow LEDs would light up.
I believe I need a new controller as this one has never worked for me.
