MAD ammeter bypass question

With that said, I used a newer style fuse, but my setup is way far from stock.
I used an 80 amp in this 1994 Ram fuse / relay box, downgraded from the 120 amp that was in the Ram. When I bought my alternator I intentionally chose the one with the smallest rating, which I think was 90 amps.
