Maybe you can take your truck to the local auto parts store and see if they can pull the DTC, then start from there
I'm not sure what level reader they have so will just have to bring it up there and see,
There is a lot of things contained within the charging system that have input to alter the charging range, really need the DTC to know where to start,

Haven't solved it yet
I am still working on trying to solve this issue, and I have tried to turn the lights on as soon as it starts. It seems like it will stay charging much longer now rather than just the length of time the Start up Cycle timer was running before going back to the discharge mode.
I have to Take the Time to Completely Read through Each of The 9 Charging Modes to determine which one is actually causing my problem.
I Truly Appreciate All of the help in dealing with this matter.

Thought it was a problem with not enough load

I am Still trying to solve this problem, when I turned my Lights On as I Drove it Seemed to Stay Charging Properly but yesterday it began to drop down to a discharging state as I Drove - Again, So now I am Spending time to Read and Review Each Video and suggestion I was Offered from everyone here. I See that the Charging System Is Extremely Complicated as compared to Earlier Models as well as my 00 Chevy.
"Would Anyone Here Happen To Have An Electronic Copy of the 2008 Hummer H2 Service Manual in Pdf Format that I Could Download ??
- It Would Be Greatly Appreciated !!!
As I said before, I truly regret not Ordering A Complete Service Manual Set When I Bought my H2 Lux New from Southgate in Edmonton.
Thanks again for all the help and suggestions so far.
The Alternator is New and The Battery is 10 Months Old.
