My motorhome control panel shows a voltage of around 4V and the whole 12V circuit is dead yet both leisure batteries show 12.8V on a multimeter test. When I connect a 240V supply to the Power Supply Unit and switch the charger on the 12V circuit livens up and everything becomes fully operational. Can anyone offer advice/suggestions?
12V system down yet batteries fully charged
