It is best to use a systematic approach. First you really have to have the battery slow-charged till it is as completely charged as it will get. Then it should be load-tested. If it is over 5 years old just replace it. Clean the connections and put it back in. Make sure the belt is not loose on the alternator. If you still have a problem then you need to have the alternator tested. Most shops will do it for free. If the alternator is OK then it will be a wiring problem, a broken wire or dirty, corroded connections. A charging problem is very often a bad battery, it just looks like a charging problem. You must isolate the parts and test them individually so you know if it is the battery, the alternator, or the wiring. If you have the Ducey alternator don't waste any time or money on it, just get a Delco.
