Re: My battery light is on.

You need to do diagnosis. Just because you replaced the alternator doesn't mean it can't be bad again. You need to check battery voltage with the car off, then with it running. This will confirm if the alternator is charging or not. A bad battery generally eont kick a battery light, it just won't let the car start. Once a vehicle is running most of the electrical is handled by the alternator.
