On my above caravan, there is a twin switch (12 volt), mounted on the end of the kitchen unit, facing the front of the 'van. One switch operates the 'floor light' but I can find nothing which is operated by the second switch - even though it does have wiring attached - any ideas?
It could be for anything. Is there a 12v socket nearby for a TV. It could be for that.
If anyone else has any ideas, let us know and we post your ideas on the website.
