The problem with the car is not that the battery drains, but that it isn't charging to begin with. What is blowing out the alternators (or voltage regulators or both)? What can cause this?

In other cars, I'd say "voltage spike" or "worn brushes" or simply replace it and forget about it. With this car I've replaced it but it's still blowing out? Suggestions?
