The cable from the battery ground is spliced and runs to both the alt and the frame. The frame cable is actually alot smaller than the ground running to the alt... So i ran 4 gauge to both places. Not reallly sure if it is a big problem but most of the trucks electrical devices is grounded to the frame. And because of that I wanted to have a larger ground in that area.
Great!, do you know if the replacement OEM cable is the same gauge number all they way or better in anway...
