So I've got an annoyance. I was replacing the bulbs in my foglights in October of 2015 and afterwards my battery light came on. I don't know what I did, but there wasn't a battery light on before I changed the bulb, but there was one after. It is the only correlation I can find. Anyway, I thought maybe it was time for a new battery anyway, so I replaced it with a brand new one. No effect. I left the battery disconnected over an entire weekend thinking the system just needed to reset, but no effect. I've since driven the car nearly 18,000 miles with this battery light on. The car starts fine. It reads normal voltage whenever I've had it tested or checked. I've taken it to AutoZone to be tested and they said the battery is fine and they can't imagine what would be the problem. If it were an alternator issue then I would think I'd be seeing some symptoms of something happening, but it starts fine in any weather. 10 degree days are no problem. 110 degree days also no problem. I can find nothing wrong with the car and I've checked all the fuses and everything I can think of. I'm about to put a piece of tape over the light or just remove the cluster and take the light out because it is annoying, but after more than a year I don't really notice it much. I'd probably notice it more if it finally turned off. Any thoughts?
