Good catch on the fuse!! sometimes I myself skip over the basics and overlooking the simple fix. another good thing to keep in your toolbox is a small bottle of Penetrox, its an electrical joint compound that helps prevent corrosion between copper and al connections, the number one killer on electrical connections on these and other euro cars. as corrosion builds the connection becomes weaker and draws more amperage, thus more heat until it fails. A little dab 'll do ya on all connections.
