WHILE DRIVING ALTERNATOR STARTED SMELLING AND RAPID CHANGES IN VOLTAGE. WHEN STOPPED AND OPENED HOOD ALTERNATOR WAS SMOKING AND STARTING TO CATCH ON FIRE. TRUCK WAS BEING DRIVEN ON CITY STREET AS WELL AS A HIGHWAY. I HAVE TAKEN THE TRUCK TO DEALERSHIP IN JULY TO CORRECT ALL RECALLS. THE DEALERSHIP DID ALL OTHER RECALLS OTHER THEN ALTERNATOR THEY SAID THEY DID NOT HAVE THE PARTS AND WOULD CALL ME WHEN THEY COULD GET THE PARTS. IT IS NOW DECEMBER 23RD AND NO CALL WHEN THE ISSUE HAPPENED.
