Battery blowing voltage regulators "why"

I agree, I think its a short somewhere hidden too. Im currently having the same problem, both with all original regulator/alternator/points, as well as after upgrading to electronic on a 66A. It was all either new or rebuilt. I switched the alt/reg to a set from a 72 Dodge with new Bosch battery, and it worked great with points for several months, but at some point the battery swelled up and the alternator fried. Gauge twitching and battery overcharging. I replaced it all again with a new distributor and all worked great for a while. Now with the new ignition kit, the gauge is twitching once more, the regulator burned up and replacement battery is leaking.

This also happened to the original owner before I bought it, so I'm starting to think that replacing these electrical parts is just a temporary solution. Next is a search for a higher quality regulator, and thorough inspection of all wires because something else seems to be the problem.
