Thanks. When I press the power switch once it says ‘Master On’ this then allows the lights, fridge, sockets and the bed release to work. There are some sub menus which show water level, battery level etc. I assume this means things are running from the leisure battery. Press the power switch again it says ‘Master off’. But I can still put 2 of the kitchen lights on at the panel. I’m ringing the converters tomorrow and I’ll talk through it with them. The rest of the info they provided was very comprehensive so I’m giving them the benefit of the doubt as the rest of the van is spot on. Mike
