I brought the truck to a Chevy dealer and they didn’t find anything wrong. Then a week ago I got the same “Charging System Failure" again and the volt gauge on my dash showed that I was losing power. I again brought the truck to the same Chevy dealer and they redid the connections that allow the alternator to charge the battery (connections in the red plastic “transfer" box between the battery and alternator). They claimed this was the issue. However, 3 days later I looked down on my dash and my volt gauge was showing 12v again.
That your altenator/regulator isn't putting out enough voltage/amps for your electrical system to work right. Usually when charging system failure occurs you won't be able to start your car because of the drain it puts on your battery. 13-15+ volts output is what most charging systems put out depending on what vehicle. Good luck and hope this helps.
