So by accident I was going overseas and wanted to make sure that my wife has enough of starting power for Chicago's winters, so I decided to replace battery and alternator. After replacing alternator vibrations disappeared. To be honest alternator bearing was good on the old alternator, so something else mush have been creating that vibration inside and transmitting it to the engine somehow. Or maybe internal diodes were shorted and were creating EMI at certain rpms who knows. So what I suggest try removing your accesory belt and drive for minute or two you will not drain your battery and see if vibrations disappear. At least you will be able to rule out alternator and other pulleys.

You can drive it during the day without running air, radio, lights etc. probably all day..sometime in Nascar some of the ignition system or charging systems mess up and they run half the race on just the battery.
I had a 76 Eldorado and the alt light came on one night around 7 pm and I drove till 11pm till it started to run like crap and finaly stalled. It had a 500 CID engine and I used the air and radio....didn't realize my alternator was toast. So you can go for a while, long enough to see if that is your buzz
