Unhappy mercedes 300sl R107 1988 fuse 12 blown flat battery

I have just had an interior refurb and new carpets to my car. It went in working 100% but during the work the battery went flat,fuse 12 blown! Have put in new alternator -but still fuse 12 blows. Have disconnected the radio/cassette and still when you replace fuse it blows again - also relay units are very hot?
Battery will not charge at all- but will jumpstart only from another vehicle, then when ignition turned off battery flat again straight away.
Something shorting?
Help please!
