Pulley Whine
I have replaced the alternator and the tensioner arm and pulley, and still have the same whine. The truck starts right up, but then shuts down soon after. Belt tension is good, and belt is in good condition. How to diagnose idler pulley and power steering pulley?
Thanks for any advice.

First confirm that the noise is from the alternator belt. Remove the belt and run the engine. If the noise goes away it is the alternator belt, pulleys etc. If the noise is still there, then something else is bad.
Assuming it is the alternator belt etc, you can put a big screw driver against your ear and press the end against the possible noise sources. Naturally DO NOT put the screw driver against moving parts and watch your body parts, clothes, hair etc as you lean over the engine.
You could also try a hose in your ear to act like a stethoscope, but usually the screw drivers works better for me.
BTW some brands of belt do whine a bit like a blower. Gatorbacks come to mind with a whine. Sounds cool.
Good Luck,

Pulley Whine
Jim, thanks for the reply. I am a complete novice at this. I am unclear on how to remove the belt and still run the engine. I thought the serpentine belt was crucial to the engine running.

You can do it for short times. Just don't do it for long, because the serpentine belt runs the water pump.
One of the easiest things to do is take the belt off. and turn each pulley by hand, is there any resistance or noise?
