Bettery came on, took it to the auto part and the battery was bad it was replaced but the battery light still on. Went back and the alternator was checked and it came out good. Light still on. Any ideas?

Thanks

I want you to complete a simple test on the alternator. The alt may be good, but the wiring to the battery (fuseable link) may be bad. As a result, the alt will test good, but can't charge the battery. This test will check for alt output at the battery so you will know if you are getting power to it.

Check it and let me know what you find.
