I got time to work on it yesterday and it seems like after moving the cable around it will turn over and run, like I have to jiggle the power cable to the starter to get it to work.
It weird that this problem is occurring now bcs it was a reliable system for thousands of miles up until the other wkend.
I'm going to take all the cables off the truck today and I will get you all that info/measurements...i think i made that cable myself so there is really no marking or way to tell on the truck
also how do you gauge what size the ground strap bcs if I remember it was a braided wire/strap?
