Here I have a 2008 trail blazer 3ss with the 6.0 motor in it, and it is awd. I'm having issues with the voltage drop I have seen everyone has at some point with these cars. These are all the things I have replaced recently battery, altinator, water pump, high volume oil pump, and relocated pick up tube. When I first crank the car up it's charging above 14v but after driving it about 10 miles tbdrops to about 12v. It was doing this before I replaced the altinator. I have a system in the car and I have never witnessed so much light flickering and battery fluctuate so much with the system on and I have had one in every vehicle I have ever owned. I can't seem to wrap my head around this problem so any pointer would be greatly appreciated
