W. Illinois | If it is an older belt drive pump it could be the magnetic pickup sensor that reads off the drive wheel. We had one go bad this fall and it would show no flow. You can unscrew the sensor out of the top of the NH3 meter and put it on the pump to check. Otherwise, call L&D Ag, they know those systems inside and out.
You might check the cable to the flow meter (round connection). I think with the tab up that 2 o'clock is ground and the other two pins should have 5 volts. It should say in the book.
