WHILE DRIVING, AN ODD ODOR COULD BE SMELLED, BUT WENT AWAY AFTER A MINUTE. CAME BACK ONCE BRIEFLY. 20 MINUTES LATER, AS I WAS ABOUT TO TURN INTO MY WORK'S PARKING LOT, MY CAR TURNED ITSELF OFF. WHEN I TRIED TO TURN IT BACK ON, IT WOULD NOT TURN OVER AND ALL THE GAUGES WENT HAYWIRE. AFTER I STOPPED TRYING TO START IT, I TOOK THE KEY OUT OF THE IGNITION AND THE CAR ATTEMPTED TO START ITSELF. IMMEDIATELY AFTER THIS, THE INSIDE OF THE CAR FILLED UP WITH SMOKE. THE FIRE ORIGINATED NEAR THE BATTERY. AN OFFICER SHOWED UP LESS THAN 2 MINUTES AFTER THIS ALL OCCURRED, AND HE SAT THERE AND WATCHED MY CAR BURN. HE PULLED OUT A FIRE EXTINGUISHER 10 MINUTES LATER SO MY CAR WOULDN'T CREATE VISIBILITY ISSUES FOR THE CARS DRIVING PAST (IT DIED IN THE MIDDLE OF A FOUR LANE ROAD). THEY TOLD ME IT WAS MOST LIKELY AN ELECTRICAL FIRE. TWO WEEKS PRIOR TO THE INCIDENT, I HAD MY ALTERNATOR REPLACED. THE NEW ALTERNATOR WAS A FORD MANUFACTURED PART. *TR
