There are a few things that are, in a way, 'unfused'. Or they are fused thru the stud-fuses in the little box next to the battery.
If you yank ALL fuses, it's gotta be one of the loads in the little box, the alternator, or maybe the pulse module.
If you have not seen it, my procedure is attached. I'm way too busy to spend too much time here right now, got a month-end deadline I am going to miss no matter what.
