Don't think you are alone with this! I think there are a lot of tinkerers like us that don't fully "know" their way around the LS charging system. The Dr44 and DR44g replaced the AD244 (large body) alternators I guess around late 2004-2005 period. You'll have to do some research on the why's of the change, along with the voltage regulator control being controlled by various modules and pulse width modulation. I've spent much of the day today reading posts on this site, going back as far as 2010. This seems to be one of the little known facts about the LS swaps. Back in 2015, when I put my truck together, I thought I had it pretty well figured out. Here it is 5 yrs. later and I'm Still learning!!
