I foregot about the alternator ground, thanks for reminding me about upgrading it too.

This might be a dumb question but here it goes. My wire from my alternator goes to my fuse box, goes through a 100A fuse, then comes back as a smaller wire to my battery. Now My question this time is, does the wire coming from the fuse box (alt fuse) actually connect to any circuits in the fuse box, does does it strictly go to the fuse box toware it would have a nice spot to be fused at, thanks...
