All they do is alternators. That is why I said call, because everyone trying to go HO without a rectifier seems to be frying alternators. Maybe the PCM has some type of voltage or amp regulation? I will be calling myself soon, once I finish getting the money together for a rebuild.

Most alternators do all the control within the alt itself - there's a sense wire for it to measure voltage at another location, like a primary positive junction, and it regulates internally to keep that junction at a set-point.
It's pretty clear the LS alternator is not like that. Rather, the PCM plays some active role in the alt output.
