which belt charges my battery or engage with the alternator

Since your model is 1993 E coupe, I'm assuming the engine is the 1.6L GA16DE. You'll have 2 topmost pulleys on the passenger side of the car. The one you want is the alternator pulley (belt is on this one) closest to the front of the car. Here's a diagram to help you: http://www.autozone.com/repairinfo/repairguide/repairGuideContent.jsp?pageId=0900c152801cdf18 Look for the GA16DE diagram, it's your engine. You can go to the store with the old belt or just ask for it. You'll need to specify if your car has A/C or not because it changes the lenght of it.
