I was having intermittent starting problems related to old battery. I installed a new battery and after starting a couple of times I now have zero electrics (ignition, gages, lights, door locks, etc) anywhere in the vehicle. I suspect a faulty busbar but can not find it in the engine compartment. Also have not been able to find anything online referencing it's physical location.
174 amp busbar location on 2004 Yukon XL.

I'm not aware of a bus bar on the NBS. The larger positive battery cable goes to the junction box on the left side of the engine (where the alternator connects), then on to the starter. The smaller, shorter, wire from the battery + goes right to the underhood fusebox.

NBS (New Body Style) is 2000-2006 model years.
I would suspect the feed to the underhood fusebox, then. I'm not sure if there is some kind of main fuse there (don't think so) but follow that wire and measure voltage along the way. I would suggest measuring voltage at the same positive spot, and with 1) a body ground and 2) an engine ground. They should read the same and that would help verify that the grounds are intact.
