Backup Camera Installation Issue
While attempting to install an after-market backup camera on my 2015 Four Winds 28A, I discovered an apparent anomaly tapping in to 12 volt power via my marker lights. I spliced the black camera power cord wire to the black marker light wire and the red camera cord wire to the white marker wire. The camera would not power on. I verified the camera worked by next connecting it directly to the 12 volt coach battery. Returning to the tap, and using a volt meter, I checked continuity. I discovered that the black (presumably negative) wires were flowing to the tip (normally positive) of the power cord. And the white/red wires flowed to the sleeve (normally negative). Meantime, the marker lights operated fine. Seems I need to flip the wires feeding my camera but I'm a bit hesitant for obvious reasons. Is it possible that the polarity of my LED marker lights are, in fact, reversed (negative)? I know that Truck-Lite makes LEDs that are polarity neutral. I just don't know if I have them and I don't want to risk blowing up camera in case I'm wrong. Thanks for any help here.
