Alternator issues

so update : I talked to the alternator guy that is handling the warranty/ repair work for the company I purchased my alternator from. He said there was a problem with the regulators hanging open. He sent me a new regulator I put it in. Still no charging. Now I know all of you alternator pros think I am spinning this too much, but I was assured there would be more damage to the alternator than just not charging. Could there be some other underlying issue that is killing these alternators?
