Aqua-Vu MAV-10 Wiring Question
I've been sorting out the birdsnest under my console as I add my LSS-1 and upgrade my NMEA 2000 network. In tying wires off to the side, I've come across one that I cannot figure the purpose of.
I have an Aqua-Vu MAV 10 underwater camera on my boat. The power cable has three wires...red, black and white. I've got the red and black fed to power the unit. The white was spliced into a wire in the console loom. I thought it might be switched power, but the unit powers up right now with the white wire detached. Nature Vision has no wiring diagram in the literature that came with the unit. Does anyone know what the white wire is/might be for? Thanks.
