it might be alternator, just take it off and get it checked for free at oreily's!

 

Oreily's and Autozone have crap testers. My old prelude's battery light came on, tested the alternator there, and they said it checked out ok, so I replaced the battery and the voltage regulator, and the light was still on. So I took a long shot and bought a new alternator... light finally went off.
