The battery light on my 12 Ram is coming on after 15 minutes of driving. This started yesterday morning. Had alt, battery and starter tested. All was good. They said it showed 12.6v or 13.6v. can't remember for sure. I got home this evening after O'Reilly's test and tested it with multimeter. I had 14.1 at Alt and battery. Check plug on Alt and had the 5v from PCM and 10.5 on the other wire. Test have been done when the light is off. Should I be checking it when battery light is on? Side note, a week ago the lightning bottle came on for 5 seconds and I had no throttle. Hasn't happened since.
