03 GMC Yukon, Battery Not Charging p1637 The "Battery Not Charging" warning & battery light flash on & off as I brake, accelerate & turn corners. I assume something may be loose. Am I correct or should I go ahead & have the alternator replaced?
You can check to see if something is loose (like battery terminal), you can use a voltage meter to double check the alternator is not charging.
you can check the alternator connector just to make sure its not a harness problem. If you have getting 5 volts replace the alternator
