In my 2021 Marco Polo I have under the left seat, to the left of the leisure battery a block of spade fuses (mostly 50A) and a relay.
I had a problem with car and leisure batteries being totally flattened and we reckon the charging relay was stuck closed, but something else must have gone.
My local installers found that the relay mentioned above had no power and the front of the 50 fuses was blown.
They replaced the fuse and there weas then power to the relay. For now they disconnected the leisure battery negative terminal.
Given that the blown fuse might have something to do with the flat batteries does anyone know what that relay is for? I wondered about the electric roof but that has not been touched for 3 months (yes I need to open it to air it and check but first the charging relay is getting replaced with a DC to DC charger - small steps).
