2007 Chrysler Aspen battery light
 

2007 Chrysler Aspen The battery light comes on every once in a while. If I turn the car off and restart it the battery light goes off. This happens every once in a while. I tried putting in a new alternator and the battery light came on and stayed on. I put back in the old alternator battery light was off but came on the next day. It went off again soon as I shut the vehicle off and started to back up. Any ideas?

What ended up being the issue? I've been experiencing this for a while now.
