there are several different earth straps around the engine bay and rest of the vehicle although i cannot exactly advise where, have you got a haynes or maybe someone one the forum may be able to help out. i would remove all these in turn, thoroughly clean contacts with wire brush and refit ensuring a good tight connection.

did you get the battery drop tested for any dead cells?

Have you got a light in the boot and are you sure its shutting off when the boot is closed?

As said above 'have you had the battery tested?' if yes then put a volt meter across the battery without anything switched on and you should see the volts dropping slowly, go through everything you can (maybe pull each fuse, one at a time) till the volts stop dropping, when you find which fuse stops it then work on that line, ie: if it's the radio fuse and it's stopped dropping when you pulled that fuse then the short is on/in the radio wiring.

hope this helps.
