64 barracuda fusible link

So the alternator cannot overcharge, and send too much current to the main splice, possiblly burning ignition switch or anything else connected to the main splice? I bring this up because one of the diagrams shown in MAD does show a second fuse link in the alternator wire:
Catalog (madelectrical.com)
However, This diagram also has the mod where the alternator output will be routed directly to the BAT. POS. stud at the starter relay, rather than going thru the bulkhead to ammeter (which I bypassed back to the batt red wire). So maybe this mod necessitates a second fuselinK?
