Andy, as you are new to this I would suggest that you call a vehicle electrician to look at your vehicle. Not knowing what has gone wrong I can't fault find from this end. You haven't explained what fuse/fuses have blown or if the electrics have been tampered with by a previous owner.
Were there any electrical problems before you tried to change the battery?
If you isolate the vehicle battery from the leisure battery, will the vehicle start?
This I'll Defend
I would prefer to say that I am British rather than European.
