your auxilary drive belt might have snapped or be extreamly worn.. That's someone elses answer. mine answer would be to check the little black ground plug on the bottom side of the alternator looking at it from the ground up past the cv axle its a gray wire with a big black plastic clip i had to cut mine and put a new female spade on. i had the same problem with my 99 2.5 v6.

Yes, it can. A completely dead battery can blow the alternator diodes, at least in older systems - I am not so certain about newer systems, whether or not they are protected against this annoyance. In any case, the alternator is not generally designed to charge a battery from scratch, but just to keep it charged during normal use. The alternator will not be completely ruined, but it will not function until the diodes are replaced.
Your volt meter reads 16 volts at the battery at idle The alternator and voltage regulator have been replaced Do you have a problem?
Alternator Output Voltage RangeGenerally, alternator output voltage is consider OK if it is in the range between 12 1/2 volts to a maximum of 16 volts.Therefore, although the output is at the maximum, you do not seem to have a problem.Usually, if the battery has had a lot of drain, then the alternator output will run at the maximum until the battery is fully charged.
Will the altnator lock up causing car to stop?
It can happen. The bearings on the alternator of my Silverado did that once, and it ended up causing the vehicle to shut down. the alternator on your car charges the battery which in turn runs the electrical supply to the car. if your alternator is damaged the battery will deliver power to the eletrical system until it no longer can and the car will stop running.if i were you i would replace the alternator,recharge the battery if it is still good and then happy motoring.
