Is the caravan connected to the car with the engine running. If so the 12 volt is isolated by a habitation relay. That may possibly have failed.

Is the battery connected the right way round.

There should be a battery condition gauge which indicates that there is power coming from the battery. Have a look to see if the gauge has registered and if it hasn't then either the switch hasn't been activated or is defective as the fuse has already been checked and found to be satisfactory.

I had a problem when we bought the caravan, ended up temporary bypassing then tried to work it out latter.

It turned out we have 14 fuses and 12 names, so I had counted down the names then the fuses to check, but I was simply pulling wrong fuse to test.

All that was wrong was a fuse blown.

I was checking fuses by testing volts one side, and testing volts the other side, however this fuse was fed from both sides, so I again missed it.

So remove fuse test and replace. No short cuts.

As I tried to trace I found there were 4 relays shown on the circuit diagram but actually 5 on the control box. So some times you get unexpected things. It only takes one relay to go faulty, so do check with and without car connected, it can help work out what is wrong.

Glad you got it sorted, well done. It's so easy to make assumptions when faultfinding and then spend ages going off in the wrong direction.

Had exactly the same with my hymer.it was the 50amp fuse next to the lesure battery under the drivers seat. It had blown after renewing the starter battery I think
