I would have to say it sounds more like a short somewhere to me. I have had 2 alternators die on me, first would start throwing dummy lights on as everything dimmed, second one just lights would dim or surge with the motor. Both times the alternator was still putting out some current but not enough to keep up with charging battery. My experience is the car will run about 5-7 minutes on just battery so any longer would tell me alternator is good. Had something like this happen with another car and it was a power wire to the radio was cut and touching a metal brace in the dash causing a daw with the car off. I would look for any bare wires touching on metal, start with areas you may have worked around recently in last 2 weeks as you may have rubbed some coating off a wire or something loose.
