I have been hearing a low pitched whining noise intermittently from the engine compartment when the motor is running. I also noticed the voltmeter needle was lower than normal, around 10-11 volts. Normally the needle is pegged right in the middle on the 14 volt mark but it was halfway between that and 0. I figured it was time for a new alternator and installed it today but alas... It still shows the same reading. Any ideas?

I'd start by tightening the belt.
if the belt isn't gripping, it will squeel and not turn the alternator like it should.
Also, is this just at idle, or does it still show low even when rpm's are >1000? It SHOULD be pumping out 14v.
If it still shows low, check your wiring and make sure everything is snug.. I use a little dieletric grease on all the contacts just to make sure
Also, have you added anything recently that might be drawing lots of power? Fog lights, wench, juicebox, etc? I know I have and i'm going to be picking up my new powermaster 150amp alternator this afternoon because the stock 56 amp alternator isnt powerful enough to even run my headlights.
