I’m trying to find out how to rewire the van to make the interior lights run off the leisure battery as aposed to the engine battery as standard.
Also can someone confirm that the leisure battery should be charging when connected to a hook up as mine currently isn’t. So would this mean that the split charger is buggered ?
I’m a bit lost with the weasty display as well it blows the inline fuse every time the tap switch is turned on ... they both work independently but when connected together blows the fuse inline behind the panel. Please help sick of buying fuses with no joy

Thank you in advance
