Hello Steve
Thanks for your advice. I've just had a look and the battery isolator switch only isolates the motor mover and not the 12V habitation system. On my last caravan, an Abbey, the reverse was true so it seems there is no standard setup. As I said, I can cut off the 12V supply to the living area using the Power pack SE switch, but I'm not sure what that switch isolates so it looks as if I will have to disconnect the battery.
