Is there anything working on 12v when not plugged into 240v? Lights? Water pump?
I have a Truma control panel that controls heat/hot water. I also have a panel that shows the state of the batteries and the water tank levels. It is this panel that has a circular knob to step thro the various monitors but when you PUSH that button it trips the 12v on and off.
