This morning I went to start up my 1965 Buick Skylark. It started just fine like always and then it did something really weird. The gen light stayed on. Also when I put it into drive and drove forward a little it made a little hi piched squeaky noise. I check the belt and it was on correctly and tight. (I know it is not a belt) I have replaced the battery as well as the alternator within the last 6 months becuase both were old and went bad. The car runs but the gen light stays on so I didn't want to risk getting stuck somewhere. Does anyone know what this could be? To me is sounds like a faulty voltage regulator.
