Thanks for the advice long, I appreciate it. Well, my inability to be accurately descriptive about my problem with the alternator hinders everyone elses ability to understand me precisely and offer a reasonable solution. So, I have narrowed the sound down to the inside of the alternator. The sound comes and goes at will and generally does not last long; maybe only seconds before it goes away. The good thing is I do not notice any electrical difficulties inside my car. Since the car doesn't seem to be effected by what is going on, I don't think an alternator replacement would be necessary; however, in the long run it may be. My biggest reason for posting is the darned noise is just getting on my nerves, lol. It's not that the noise is very loud; it is actually at a low volume, high pitch. I can barely hear it if my vent is closed but when it is open I can hear it a lil better. I have asked my girlfriend if she hears it while we are driving and she says no. So it's almost like I am 'trying' to hear it but I know it's there. I guess I've just been hearing it for so long that I know what to listen for.
Either way, I appreciate everyones' advice and taking their time with trying to help me determine what the problem is.
