The fridge is probably wired to the leisure battery on a 1991 caravan. Were you running the fridge on 12 volts? This will flatten the battery very quickly. The only time the fridge should be on 12 volts is when it is being towed. If you are without EHU, then run it on gas. Do you have 12 volts at the 12S plug on the car? The switch should be set to CAR to charge the battery. This will turn off the 12 volt electrics on the van. Mine is wired in a similar way, although I do not have a VAN/CAR switch. I intend to rewire it over the winter to the later specification as I left my fridge on 12 volts for a few weeks in storage and ruined my leisure battery.

I think I may have left the switch on "van" when I tried to charge it so maybe that's the problem - I will try charging it with it on car when i go next time - I have no way of testing if there is 12v at the plug on the car, although as the towbar is less than a year old and fitted by a guy here who seemed to know his stuff I am fairly confident about it being "live". If ithe caravan electrics were working correctly surely I should be able to run the van electrics from the car battery when the engine is switched off?
I was running the fridge on gas while at the site, but turned it on to 12v with it connected to the car just to see if there was any power coming into the van from the towbar
Thanks for the tips!

Agree with the above, Your fridge should only work on 12v when connected to the car with the engine running, The switch should be in the car position to charge the battery and this can be live without the car running but most have a split charge relay to stop the van draining the car battery

The 12V supply to the fridge and the van battery charge are operated by a relay to prevent the car battery being discharged by the caravan when the engine is not running.
As mentioned earlier the fridge will usea lot of current, they should run on gas or mains on site.
