hello peeps!
So last Friday, I drove down to SoCal and after 420 miles, battery light came on. I pulled over, turned off the car and started it again, battery light came off. Then after driving another 25 miles, it came on again. And then I did the same thing, turn off and on the car. Worked the 2nd time! I got to my destination which is 15 miles more. Parked the car, called it a day.

After 12 hrs, started the car and viola, battery light remained on. I took it to autozone to have my battery and alternator tested. Autozone charged the battery first because it was 71% only. While in diagnosis, the guy made me start the car and miraculously the light wasn't on. The battery and alternator checked out ok.

So I decided to take the car for a spin, about 10 miles of driving light came in again! I pulled over, did my trick and it work. On my way back to my apartment, it came on again but when I exited the freeway, I went on a stoplight and when it turned green, battery light went away! I went to my parents house which is about 15 miles and back, battery light didn't come on.

Is my alternator going bad or my battery?
Are there other ways to test my alternator?
Is it possible that the belt could be the culprit? -Belt looks ok and tension seems right
What other things do I need to look at?

note: driving ~70mph when the battery light came on (driving to my parents' house ~70mph battery light didn't come on).

Need help to figure this out and fix it. Thanks
