If you don't have fuel injection, pull the hot (red) post off your battery. If the car goes dead the alternator is not charging the battery.
AnswerIf you have a local parts store they will test it on the car,most for free.check the spark plugs and wires, if they are faulty then it will cause your alt. not to charge, i had the same problem, i bought a new battery,got the alternator tested and it still would be dead, after i changed the spark plugs the problem disappeared(AND IT THE CHEAPEST) i did all of this in -40c weather
