The alternator warning light monitors the charging system. When the light comes on it means the alternator has failed and you are running on the stored energy in the battery. You'll have anywhere from 5 to 30 miles to get to a repair shop depending on how many electrical devices are using the batteries power,ie.radio,lights,wipers,etc.
