Well, finally got a chance to do a little work on it. It's also kind of nice to have another 2001 Silverado sitting right next to it to do a little comparison/sanity check. Oddly, found NO parasitic loss today on the truck in question, which I find odd. But one thing I learned, which leads me to believe I may have mis-measured the amperage last time. See post #9 for my conclusions - I've chopped them out of here and re-written more clearly below (I hope
).
