There's this whining noise which has begun approx. 2 days ago. It is most noticeable at or past 3k RPM. I notice it less during gear change, at which point the noise vanishes for a fraction of a second. I'm thinking it could either be my alternator or my belts.

Also, is there a way to test the alternator? As far as I know, there is not, which means that when an alternator dies, so does our battery because it will drain it? Is there anything I can do to prevent this from happening?

Suggestions are welcome. THanks

 

Sounds like alternator. Have it checked for free at Advance Auto or Autozone.

 

at advance auto, they told me you have the take your alternator out and bring it to them to test it!!
