Well, that is the right place for it, according to
the simplified wiring diagram.

So, are you using a 30 amp fuse? Is it in a new fuse
holder, one that's rated for 30+ amps?

Did the bike have any electrical problems before
you re-wired it?

And, exactly when does the fuse blow? Right after starting,
or a little while after that?
