Currently using the 750 for guidance only and mapping coverage when auto is engaged. Im using a toggle switch to control an electric clutch on the seed cart for my air seeder. How would i get the 750 to map coverage when i have the switch on an am seeding?

Alternatively, would the 750 be able to control the switch itself, turning the clutch on/off when i get to the end rows?

Edit to add- or would a field iq be required to get the 750 to control it?


Take power off the toggle switch and run it to a 12V automotive type relay. Wire the coil of the relay with one terminal going to a wire that goes ON/OFF with the switch and the other terminal to ground. That way whenever the switch is ON, the relay becomes active and its output terminals are connected. Run a pair of wires from the output terminals from the relay to Pins 10 & 11 of the Port A Deutsch connector. Then go into the 750 and set coverage mapping to switch and active high i believe.

You will have to get a field iq to run it automatic.
