If you want to fuse it it'll have to be a big fuse. At least the max amps of the alternator. All the charge from the alternator to the battery goes through the guage. I would think you'd want the fuse on the alternator side of the ammeter. If a wire shorts there you would have full power from the battery going through the gauge to ground, if it shorts on the other side you'd have the alternator power going through it, which it's rated for.
