According to Van's RV-12 wiring diagram, the Dynon SkyView display is powered by two wires, one wire to pin 1 and one wire to pin 20. The wire connected to pin 1 is switched by the Avionics Switch. The wire connected to pin 20 is not switched and is hot whenever the master is on. Does anyone know why it is wired that way? The Skyview display in the RV-12 is not wired in accordance with the SkyView System Installation Guide which says,
Obviously the Skyview works fine the way that it is wired in all of the RV-12s currently flying. I am just curious about the reasoning behind switching one power wire and not the other. Since pins 1 and 20 are adjacent to each other, most likely they are connected together inside of the Skyview display. If so, the wire going to pin 1 will be hot whenever the master switch is on, regardless of whether the avionics switch is on or off (if the wiring diagram is correct).There are two unterminated solid red primary power input wires (to reduce current loading in each wire?these are not for redundancy and both must be connected to the same power source)
