Just finished putting our 1990 Silverline Nova princess caravan into hibernation. Husband has had the battery charger on with the battery still attached to 'van with rocker selector switch off & mains switch under seat off.
When I checked inside the fridge there is a huge block of ice and I can't open the freezer door. The green switch was in the on position & dial at 7. I assumed that if the switches on the caravan power supply were off the fridge would be off as well.
if that green switch on the fridge is lit up when in the on position it must be getting a mains feed from somewhere or you have a major problem if the van is not on hookup. Curious as to why you would use a separate charger why not put the caravan onto a mains hookup and use the onboard charger.
------------- here today , where tomorrow?
yet another full timer,
