The first thing I had done was take the truck to two diff auto parts stores and have a full computer scan n printout of the battery checking it entirely and the alternator. The battery terminals are super clean and are all making great tight contact. I really believe something is pulling too much load or either it's grounding out or there's a bad relay. I noticed there's a relay under dash near brake pedal to the left that stays hot like temperature hot. That means it's under heavy load.
It's one of these on the right side I think the top one but can't remember
Also I noticed the battery does not fill up the battery tray all the way I wonder if it's just not strong enough. It's pushing like 650 cca or ca il have to check specs but when I ran test it was pushing out exactly what it's rated at.
