I just had to replace my alternator and the battery light was coming on when I had slow engine speed (under 1000RPM)...It gave me little warning and completely failed after 20 miles, then the battery went dead and , of course, the engine stopped...
Replace the Alternator before you get stranded as what happened to myself...
check the connectors and wires first. make sure their clean and tight. if beltis tight it should be ok. have alternator tested.

It could be a loose serpentine belt. Or if the alternator is going out either way its most likely a charging problem.

Remove the serpentine belt and check the belt and pulleys for damage. While the belt is off, turn the alternator by hand listening for the noise.

Yes. If the alternator is dead and you drive the vehicle, all the power is coming from the battery and it will eventually drain completely. Also, if a diode is shorted inside the alternator, that can drain a battery.

Why would a Mercury Sable Wagon be making a squealing noise and the battery light keep coming on after changing the serpentine belt if the alternator is OK?
I would suspect one of two things. Either the replacement belt is not the correct size or the belt tensioner is bad. The squealing sounds like a loose belt which would also account for the battery light. possible bad battery causing the alternator to work too hard
