Alternator flooded...making high piched whine??

[diego]

Recently we got a huge rain and it flooded out the street where I lived. The street was about a 2-3 foot river and I drove through it. When I got home I let the X run a while to make sure everything was ok. Later that night I drove it and it seemed fine until everything started going extremely dim as if my battery was dying finally I lost all power accessories including head lights. I pulled over and it started running extremely rough so I revved it up for about 10 seconds and all the power came back on and ran perfect the rest of the night. The next day I went to drive and had a high pitched whine coming from the engine compartment like the sound you can hear through speakers in a car of the engine??? Its been consistent since that day and does not go away, the alternator in not losing any of its capabilities just a horrible noise....any idea of what to do, replace it or lube it maybe?? maybe the pulley but seems to be coming from the internals??? Maybe not even the alternator but I doubt any thing else since I used a stethoscope and get the highest sound on it.

take it out and take it to auto zone and get them to test it on their bench tester.

Yes and no the Machine they use to test alternators in the car isnt the most acurate thing ever. I dont really trust it like i do the bench tester. If it comes to it im sure they would let you take it out in the parking lot. They dont mind here in mooresville and at the one where i work.
