So I went out and disconnected all the batteries again and swapped in the voltage regulator off my reman alternator. Hooked everything back up and fired up the truck. Immediately the V gauge was almost rock solid around 28V.
Before the V gauge would bounce around between 24 and 28v wildly, until the huge spike under load at speed that tripped the trans codes.
I dont still have all 4 batteries connected and noticed while driving the truck back to the house that the V gauge was mostly around maybe 27.4-27.6V. So next step is definitely stepping down to 2 batteries to see if the alt can keep up then.
For now hopefully a pair of the 24’s will suffice. I’ll start working on getting a fresh pair of 27’s.
I still haven’t done any actual highway testing, and after all this I'm going to have a hard time trusting it until its got many MANY uninterrupted miles under its belt, but this looks the most promising so far.
