400 amp fuse is way to big for a say 130 amp alt. Need a 150 to be safe. That way if there was a problem it would tip the 150 amp fuse before melting wire. Your 2 gauge would never take 400 amps of power so it would burn up way before ever tripping a 400 amp fuse.
I will check the fuses. They might be 150 amp. 400 just sounded wrong as I typed it.
