Stop in for a cup of coffee

All this talk of wiring woes, has me thinking I need to implement a fuse on my 66. Everything inside the car, runs off fusable link. The Amplifiers in the trunk have a 100 Amp fuse. The headlight relays are fused, BUT the line from the ALT to the batt is not. I have a 100 AMP Alt. Modified wiring is used. No Amp gauge.
All this talk has me wondering about wiring upgrades. I plan to run EFI, sound system and aftermarket lights, AC and gauges. Plan was to upgrade to a 200 amp alternator and dual batteries.
