On a system with an alternator the BATTERY has to be in good shape for the alternator to charge. You can take your battery to an auto parts store and they can check this for you. You must put the battery on a charger first before doing this. If you have a small charger leave it on for about 5 hours then take it to the store and have them check it. They will be able to tell you right away if it's good or not.
