You've lost one or more diodes in your alternator. At idle, the remaining diodes cannot put out enough voltage and current to keep the battery charged, which is why you see the battery light.

well now we r curious on something with it we thought it was the alternator but now wen you just open the hood it will sometimes shut off or if you wiggle a wire s0o we are second guessing but i think it may be just a fluke for it to shut off

Another thing to always check if you're having a charging issue is the battery and starter cable connections. Make sure they're all good, clean, and tight. If there's a lot of corrosion built up, that can drop your current a bit, and a loose connection can cause intermittent problems.
