There is also an isolator switch under one of the seats next to the battery compartment.
As I say, don't know if that helps, you may have already checked those but if not, that's a starting point.

Exactly, on older caravans there will be a switch panel.one way will give you mains power, a second setting will be for towing, i.e. for keeping the fridge temperature cool, and a third setting will be battery. Get a volt meter on the battery and see what power output you have and take it from there. After that it's a matter of going through each circuit in turn , as the above poster has already said.
EDIT. Do your lights work when connected to the mains Mike? If so test the battery as I said, and if your battery has the quick release type connectors, check there is no green corrosion on the inside of them, I discovered this on my 9 year old van last year, no lights coming on on battery, tested it and it had good output, removed every fuse and checked it, eventually came across the fault by accident as I moved the q r connector and the lights came on.
