So my alternator was dying, badly, my stereo would cut off while driving, no battery light.
I replaced it with a Duralast, but after the battery light came on. The car does not die, has 14.5v while running, and the battery tested good.
The ELD seems to be fine as it reads the same voltage before and after it. I have no p1297 or p1298 code, just the battery light.
Setup:
G1wH dash cam, running most of the day
400w amp
4300k HIDs

I know this is straining on the battery, but doesn't a battery light indicate a chagrining system fault? Why would it come on after "fixing" the charging system?
