Burned bulk head connection

Some do not agree with the mad article and if possible I would like to keep my ammeter. That's why I posted the wiring diagram with the parallel system.
With Ammeter or without, most important now, I want the wiring repaired and safe.

Thanks, Wolfgang
It always helps to know what year, model and options are on the car.
From your photo its obviously not a 63 or 65 which had a better connection than most other years.

The usual bulkhead connector terminals are small for the current they have to carry. But the terminal at the alternator output stud is usually pretty big. If that one is also burnt, lets see it. Certainly glad to help you do a parallel bypass (like Nacho suggests) but also would like be sure there is not some excessive load that has caused this overheating.

Since the bulkhead connector is damaged, but not badly, I'd leave that as is and run the new line through a grommet like the some a-bodies rear defroster grids got.
