Try and try again, I can't find a listing of the ground point locations...I need this so I can thoroughly clean the ground points knowing that is the issue I'm having causing random dips in power. I have a 160amp alternator, Optima Red Top and 1/0 gauge wire on the positive feed to all 3 major locations. I know I still have to upgrade the negative side, but for now a cleaning will do and 200k on the car certainly caused extra resistance with breakdown. I know of the body one near the battery, can anyone else list exact locations to clean and even possibly provide pictures of the locations? Thanks.
