Haven't done the cable disconnect, the alt has been professionally bench tested multiple times, its good. You are correct, theres not much in the charging system, but when power isn't making it from point A to point B, it can be a challenge tracking down the culprit, especially without decent schematics. I have a Haynes, doesn't have much at all about diagnosing problems. In fact, if I went only on what the book said, I would have declared my alt a dud, as the only testing procedure was measuring output at the battery - That tells you if you have low output or not, true ,,, But doesn't take into account that the problem might be in the wiring. Regulators are built into most modern alternators and thus aren't easily serviceable.
Dr, the alt was professionally bench tested and passed with flying colors. Its 2wd, I'm a member of a 2nd gen Ram forum, haven't got much help there.
My Haynes does say theres a fusible link between alt & starter, I have yet to find it.
