Anyone Running A Mechanical Voltage Regulator 67 Dart 273 2bbl

I tried one of those. It worked fine until I lost a good ground to the firewall. It overcharged the battery, boiled the acid out, made a mess under the hood, ate the wrinkle finish off my drivers side valve cover, and blew a bunch of light bulbs out. It was charging 17 volts. And all because of a bad ground.

Would that be any different with a mechanical or even a factory regulator?
