Lights dimming and brightening and volt meter swinging

My volt meter is swinging between 15-17 volts and headlights are dimming and brightening. I load tested batteries and they show good. I pull alternator and had it rebuilt. Still doing the same thing. Any help would be appreciated. 2002 duramax
