So today I was working on running an extra run on 1/0 + and running the ground from the battery to the back instead of grounding it in the back so it will be a total of 3 runs of power and 3 runs of ground....so while uninstalling the ground ( under the driver side passenger frame area) I notice that the ground was super corroded just broke right off once I touch it...I guess I should of rubberized that area do to the fact that it would be exposed to moisture...I will post pics once at work ... I'm still learning
