Voltage regulator smoking?
I’m not an expert, but the very same thing recently happened to me in a ‘67 barracuda. Round back alternator, and the mechanical voltage regulator. I think that regulator failed, making the alternator overcharge the battery at 17-18 Volts and that fried the main power wires at the bulk head connector. Melted the plug. I was dead in the water after that.
I fixed the bulkhead and put a new mechanical voltage regulator and it seems to be okay. For now. The one I got from summit, has Made in the USA stamped on the back of it. How accurate that is I do not know.

There are other fixes I did with the electrical but I will let others post who are smarter than me.
