Pimped my grandma's ride
Hey guys, it's me again //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Over Christmas break I will be finally getting to some major electrical upgrades to my system. I plan on installing the Big 3 and running positive and negative wires from my front battery to my rear battery, all SHCA 1/0. After doing this, will I need to (or rather should I) ground the rear battery to the chassis in addition to the ground from the front battery? If so, why? I know my fair share about electrical systems in cars but I'm just not sure about this question for some reason.
