Battery light is on, but alternator is charging
My battery light has started coming on lately while I've been driving, but my current tester shows that my alternator is charging. With the engine off, it reads 12.5V, with it at idle, it reads somewhere between 13 and 15V (it has kind of a vague scale).
Nonetheless, even with just headlights on, the battery light comes on-- and when I test the current with headlights, fog lights, and stereo on, it still reads above 12.5V.
What the heck? I've replaced both my alternator and battery in the past few months. Thoughts? Thanks!
