my battery is good and alternator as well...but my 2003 yukon keeps cutting out...sometimes it gives battery not charging warning
So the vehicle stalls on occasion and sometimes the batt. light appears on the dash before this ? You could get a quality alternator replacement , make sure the batt. is good and charged before running the new unit , also scan for any codes even if the light ain't on .
How do you know that the battery and alternator are both good? Have you had them tested?
