Mega fuse blown

Hi guys the L322 tdv8 is playing up ,she would not crank over last week just the dreaded click on the key so 1.battery fully charged
2.replaced the starter motor and still just click
3. got new alternator but prior to fitting replaced 400 amp mega fuse on positive lead and hey presto she fired up .But went to fire up today and boom no start and 400 amp fuse blown could this be a dodgy earth lead in the drivers side wing and it got wiggled when starter was replaced and gave enough to start .Any advice would be great as I need to get her up and running as the wife has a horse show this weekend.

I doubt a bad earth would cause a 400 amp fuse to blow, it takes a serious amount of energy to blow a fuse that sized, a bad earth would reduce current flow.

Dodgy starter shorting out?

It had a new starter fitted last thursday

just because it's new and shiny doesn't mean it's any good

That doesn't mean it's not faulty.
