Bit of a head scratcher this one!
Today I have just finished sorting out the electrics on the car, so now I have a fully functioning 12S socket.
On testing, fridge works - well at least it draws current, did not seem to get too cold but then I am led to believe they are not all that brilliant on 12V anyway.
But putting a meter accross the battery showed no voltage rise, not even a 0.01 of a volt increase. Made sure all switches on the zig unit were in their corect positions but nada.
Putting the 12V supply selector from caravan battery to car battery, and I was able to power the caravan from the car, which seemed to prove that the supply was getting through.
All fuses on the zig unit were checked and seemed to be OK.
I even disconnected the caravan battery and put a meter accross the leads, not a single volt. In all other respects it seems to be OK - charges off the mains via the zig unit no problem, powers caravan fine.
Any suggestions - before I just wire the battery direct to the 12S plug!
