Adding fuses

I’ve recently posted about some electrical issues, notably my under dash wiring harness was melted together from the bulkhead connector to the ammeter. I’ve now repaired the harness and reinstalled it and, needless to say, I’d rather not have to do that again.

I have made the following mods to my 1973 Swinger factory wiring:

1. Ammeter bypass, wires are soldered together.
2. Bulkhead bypass, charging wire is 8 gauge with a 12 gauge fusible link.
3. Headlight relays.
4. Ignition relay.

If I understand things correctly, I have now eliminated most of the current going into the cabin, including battery charging current, headlight current, ignition circuit current, etc.

This leaves my heater blower, windshield wipers, radio, dash lights, brake lamps, turn signals, interior electric circuits, etc. The windshield wiper is protected by a circuit breaker built into the switch, and everything else is protected by the fuse box.

What remains completely unprotected from a short to ground are the wires that run from the alternator to the welded splice branching off to the ignition, headlight switch and fuse box. The wire from the starter relay lug is protected only by the factory fusible link.

I’m looking for opinions. Should I add a fusible link to the wire running from the alternator to the bulkhead connector? Or should I add inline fuses to both this wire and the wire from the starter lug to the bulkhead connector?
