Why does my Megane blow its 80 Amp fuses?

I have 2004 Renault Megane and the 80 Amp fuse that's connected to the positive terminal of the battery keeps blowing. Any idea why?

It's blowing because you've got a short somewhere and it's protecting the wiring. Or you may be running something that's taking a very heavy drain. Suspect the aux socket or cigar lighter socket. Could also be the starter motor or the starter motor relay.
