When I bought my Freedom Sunseeker brand new in early 2010 I removed the 13 pin plug and replaced it with a 7 pin to tow with my existing electrics. I am getting 13 pin electrics on my new car and am having difficulty working out which wire is which as the colours are different from any diagrams I have found. The road lights seem standard but I have had to try to work the others out. I think that I have found the fridge (brown and red) and fridge return (thick black and white) cable by connecting a car battery to the most likely candidates and seeing it come on (when I flick the red switch on the fridge with a picture of a battery on it- I assume this wouldn't work with the leisure battery disconnected and the continuous 12v circuit but not the fridge circuit powered?). There are two cables left. I suspect that the thinner white one must be the return for continuous 12v power and the remaining 2-tone (I cant remember what colours now) wire the supply for 12v continuous power, but when those two are connected to the battery nothing comes on (surely the interior lights should work?) and there is a spark, perhaps suggesting a short circuit or a big draw? So, firstly, please could someone with a similar caravan tell me which wire is which and , secondly, do you think I should just tape up the presumed 12v continuous wires and leave them disconnected or might that cause problems elsewhere?
