The charging system drops voltage when the battery is charged. Ideal voltage is 14.6, but i have never actually seen it with a meter, usually 14.2 or less depending on the vehicle. Now as i am driving the vehicle down the interstate going 70 to 75 the cars computer conveniently shuts down my power steering and my abs breaks.
I Started It And It Ran For About 4 Minutes And Then The Service Battery Charging System Came Up, I Checked My Aeroforce Guage For Voltage And It Says That It Was At 12.1 Volts, Then When I Put The Truck In Gear And Put A Load On The Motor It Fired Right Up To 14.2 Volts.
I went and got it checked the battery is fine and the alternator is fine, i'm just curious to know if any of you know why? Now the car wouldn't start, just as with any dead. Could this be a bad alternator or fuse?

From The 2014 Gm Repair Manual:
We started up the engine to charge the battery and got the error service battery charging system. If thats ok, then the switch or the circuit board is the problem. The most used is the charge mode:
