If you mean Pin 4, I think this is correct. It should run the caravan lighting, pump etc when the engine is not running but not when it is running.

If you leave the 12S plug in the car socket, it will run on the car battery and not the caravan battery.

Do you have the twin 12N & 12S sockets fitted or a single 13 pin socket with the 12S circuit incorporated?

Pin 4 is inside lights etc and battery charging. There should be a habitation relay in the caravan which senses if the engine is running. If it is battery charges, if not lights work.

Pin 6 is fridge which only works when the engine is running an that is sensed by a relay in the car.

The caravan relay does it, there is no battery connected when the test circuit is plugged In so there is no relay to close and charge the battery.
