Our '68 Land Yacht (28ft) was being lived in by the previous owner. As part of this arrangement, they decided to use a
12 volt battery charger for the
12 volt supply rather than buy a new battery. I have now purchased a new battery and have several questions about how to correctly wire/attach the cables to the battery.
My first question has to do with where the battery actually sits. Based upon the wires (4 total, 2 red and 2 white) that come down from the the top at the rear, I suspect that was where it was at. However, the charger was placed behind the wall (access via a door in the bathroom) and was taped to two other wires (1 red, 1 white) as the "connection".
The problem I now have it that when I hook up the four wires in the back, sitting the battery on a platform I built so it will be above the various water lines/pipes that are in the compartment, I still have the two wires that are near the electrical box. Are these part of the "Univolt" system? When I check the battery level on the control panel, it started out as good, but after a few minutes of running the lights, checking the water pump, etc, it was at fair.
How are these wires hooked up? I have as of yet not hooked the trailer up to a proper 110 hookup and have only used an extension cord to run a clamp light, a fan and a radio while we work on cleaning the interior.
The four wires in the back easily reach the battery and when hooked (2 reds to positive, 2 whites to ground) up the interior lights work fine, but the outside "running lights" don't and I am certain it has something to do with the other two wires, which won't reach the battery. I am wondering if the previous owner didnt' unhook the wires from the Univolt system so they could hook them up (taped with electrical tape) to the battery charge.
Any help/knowledge in this area will be appreciated.
