Forgot to add that I did not fuse my alt + to battery +, but I had 4/0 welding cable (500 amp rated) with giant 4/0 copper lugs that I had to use literal bolt cutters to crimp. I could've probably used those lugs to tow a vehicle, and they probably wouldn't have come off, and they were well secured. A lot of people that I've seen do not fuse their battery to alt, but it just depends on how you do it. Sometimes it's very hard to fuse the alt, because the alt can be in very awkward places and obviously the proximity to the engine for a plastic fuse holder might be a worse problem then not having one. For alt to front battery, I recommend you use tons of zip ties, so that you can tie the + alt wire to a bunch of different points that are already there for other things for wire stability. Usually there's plenty of locations and other wires under the hood where you can very well stabilize that wire and keep it from moving at all. If you could fuse it, I guess go ahead and do so. Just make sure your fuse holder can take the heat of where you put it.
