Hi everyone. We have just returned from a weekend away where we had no electric hook up. My caravan is a 2007 lunar clubman and we ran the water heater and fridge off gas and used the master switch for water pump and lights. Everything fine for first 2 nights and on the last day we had no power through the master switch at all, couldn't get the battery meter too read anything not even flat. The battery however powered the motor mover and I used it for about 10 minutes too get the van on the drive at home. So if the battery isn't flat why couldn't I get 12V power into the van? I was checking the meter a few times during the weekend and the battery was good. Any help would be great
