Replaced battery in January. A week later, the battery light would come on after driv9ing about a half mile, go out and stay out. Began to happen more than once. Research led me to believe the alternator was suspect, so I replaced it - didn’t know if it was the original or not. Car has 82K.
Light still comes on, now more than often. Had the charging system checked; all came up OK - no codes stored/tripped. Mechanic had the car for three days, of course, they could not duplicate the issue.
Now the light comes on when first started, goes off after about a half mile of driving. Comes on again sometimes.
I do notice that with the auto on lights, when I step on the brakes, the headlights dim, so I pul the car in neutral at stop lights, or in Park, if it is a long light. Thinking maybe it’s related to the auto light wiring? I park in a garage while at work, so the lights come on when I leave, and the battery light pops on again.
What is the issue here?
