Kentucky | To check the relay module all you have to do is power the relay. On a reverse polarity sprayer the 12V signal is swapped between two pins at the boom valve which correlates to 2 pins on the relay module. The relay module has a 12 pin connection, Power, Ground, and boom sections 1-5. The 12V signal is swapped between two pins on the relay depending on the state of the switch. I have been unable to test this far since I believe my problem lies before the relay. My signal is dead before it ever gets to the booms. The boom valves stay on and the pump turing on/off is what determines whether the sprayer is spraying or not. | |
