69 Cuda wiring problem

I am just curious for the reason for the "Mad Max" wiring bypass.

Because ALL the alternator output current goes into the passenger compartment through the bulkhead connector on the big black wire, and must pass through what amounts to a 1/4" flag terminal, then back OUT through an identical terminal on the way back to the battery. The black terminal especially is under heavy load, "let's say" a cold winter day, you maybe had a bit of trouble starting the car, the battery is low, you are on the road to work running the radio, the lights, the heater, etc, so the alternator is running "full tilt" to recharge the battery, run the lights and other accessories. MANY of these become damaged, some beyond function.

My first experience was in the early 70's with my 70 440-6 Roadrunner. I ended up drilling out the bulkhead connector for those terminals, and running solid wire through them. This obviously was before Al Gore invented the internet

The problem is amplified because how old? are these girls? And folks put heavier output alternators on them, as well as added accessories like Great Big stereos, electric pumps and fans, and ??
