I think I have about everything to do the Big 3 upgrade. Still looking for a waterproof ANL fuse holder though.

I have been digging around for the "correct" size of fuse to use between the battery and alternator using 4 gauge wire.

I am thinking I am supposed to use a 125A fuse.

Anyone have input or suggestions
