Well I've decided to do the 2 battery run in parallel set up first, I have a warn winch so I'm sure I'm gonna need it. Well I know I won't ever use it because I'm a poser that lives in LA haha. But anyway, as far as the ground, yes its all junctioned off at one bolt at the roll cage, then from their it bolts onto one of the transfer case bracket bolts. So techincally its grounded off at the rollcage and the frame. The rollcage is powdercoated yes but, inside the threads where the bolt goes through isn't (but I know there could be corrosion between the top rollcage and the lower rollcage supports. I could just run another distribution block for the grounds for ex: both 4 guage grounds go into the block than into 0 guage wire which will go back to the - on the battery. What do you think of that? I would imagine that would be the "ultimate" ground no? lol Still trying to decide whether to use that solenoid isolater, the shop won't let me return it.
A guy told me one time "don't let yourself get attached to anything you are not willing to walk out on in 30 seconds flat if you feel the heat from around the corner"
