Two weeks ago I purchased a used 2003 Coleman Sedona (checked roof very carefully, and everything seems fine). The previous owners used it sparingly and never used a battery. I would like to take advantage of that option, but i don't see where the wiring is to connect a battery. I see the option of switching to 12v, but for the life of me, I can't figure out how to connect one.
On the tongue of the trailer where the wires for your vehicle plug come out of the frame, there should be a black and a white wire that end in a small white plastic clip. These are your battery wires. Go to a Fleetwood folding camper dealer and buy the matching wire harness. The wire harness consist of two wires (one black and one white), the plastic connector, a self-reseting circuit breaker (on the positive wire) and a ring on each end to attach to the battery terminals. Connect the wire harness to the battery terminals and then plug the two halves of the connectors together. :)
