Hello to everyone from a newbie here. I'll get right to the point. Yesterday my battery light came on and has stayed that way on my 1990 Integra. I replaced the battery which was bad yet the light is still on. When the RPMs are at 3000 or higher the light goes off until the RPMs drop below 3000. I am thinking my altenator or voltage regulator are bad. There's a lot of talented people on here so I knew this was the place to ask for advice. Anyone have any suggestions? Thanks, CJ

Take it to Autozone, they will check your battery and alternator for free. Also they can run your ECU for codes(free). Since you are getting a light, a code probably registered so that might lead them directly to the source of the problem.
IMO it does sound like your alternator though.

Sounds like excellent advice to me :bigthumb:
