split charge relay stuck open, so allows the van to try starting using the leisure battery. this draws more than 30amps so blows the fuse. could also of damaged the control panel etc

try replacing the split charge relay first

any local auto electrician will be able to locate and change the relay in a few minutes. they are normally near the vehicle battery although not always obvious

on my van for instance there is a flap in the floor behind the drivers seat and its in there. just follow the wire from the battery
