Alternator questions

I have recently had some "timing" issues. First began with a backfire and "pop" from under then engine, then a rough idle until it died, and now a "grinding" or "flopping" sound coming from the alternator I think. I have the backfiring issues under control (I had a failed spark plug stemming from a shorted plug wire). During the process though I have gotten a MAP sensor voltage code, which led me to replace the MAP and CPS sensors. But I still get the same codes and it seems a little sluggish eventhough it runs much better.

This all happened about the same time as the "grinding" or "flopping" sound and I then thought that maybe the timing chain was going bad and banging the side, but I removed the belt and run it for a little bit and did not hear the noise at all. It is really obvious when I deccelerate at stops. To me it sounds like it coming from the alternator so my question is could I have a bad bearing in my alternator that is caused a voltage problem and the noise? The gauges read normal and it always starts.
