2015 xl denali - ANOTHER no crank - no start issue! Scratching head!! - SOLVED

I went through a lengthy troubleshooting process and eventually replaced the main battery's negative cable. I figured if I could jump it from my jump box it had to be a cable issue since all of the battery voltages were good.

Just to update, my new battery cable didn't solve the problem, so I think I've probably got an iffy starter.
