In my old, old trailer I'm changing out the lower unit Magnatec 6345, to the Magnatec 7345 converter. This unit is used for sitting in down at the lake, so I don't want to change the converter out for the newer types., and the 7345 is new and was free.
My problem: The 6345 has three wires coming from it (blue,red,white) the 7345 has only 2 wires (blue,white). I have replaced the DC distrubtion panel to go with the 7345.
My question: How do I wire it and why don't I have, to have the red wire.
