Near Intersection of I-35 & I-90 Southern Mn. | A relay can be used to make the polarity reversing valves work with the Ag Leader system. They are not that expensive. One would be needed for each valve.
The relays would be a 12V DPDT relay wired in the "criss cross" fashion. Probably confusing for those that have not worked with relays. Basically the input terminals go to 12V and ground. The outputs terminals are wired criss cross with each output going to the valve. This way the relay sends +/- to the valve when the relay is relaxed and -/+ to the valve when the relay is activated. The coil goes to ground and the Ag Leader section cable.
