2005 Corolla Battery Light

[cora]

My battery light is on in my 2005 corolla s. And I have replaced the alternator and the belt and battery, what else could be the problem? The tensioner is good also.

Could it be a faulty altenator from Napa? It checks out that it is the same, but is it different internally?

Advance Auto Parts or Autozone will test the battery, alternator and starter for you for free in about five minutes to pinpoint the problem.

Is the battery going dead and not starting the car?

Never randomly replace parts hoping it will fix a problem, as this can get very expensive, end up with perfectly good parts in the trash can and your wallet being a lot lighter.

Always diagnose before doing anything.

it needed a new alternator in the first place because it wasn't putting out. and it drained the battery dry. so I replaced both. I am mechanically inclined, and im no parts changer
