[QUOTE="01 S 10, post: 5361187, member: 584353"] the CHASSIS [I]IS[/I] the FRAME people... [URL="http://www.merriam-webster.com/dictionary/chassis"]http://www.merriam-webster.com/dictionary/chassis[/URL] so this isnt a chassis vs. frame vs. 1/0 wire. I havent had any issues with grounding my 2 batcaps 2000's in the back to the frame directly. i only have 1 positive 2/0 run of welding cable going to those 2 batcaps in the back. 12v+ full tilt with 200amp alt, on over 4kw rms. but i havent tried running a ground to the front batt to see if there would be any difference. the main reason why i would run a ground from the front, would be to run a ground directly from the alternator casing to the rear batteries. i wouldnt really benefit just grounding to my optima red top up front. my biggest power source are the 2 batcaps in the back which are grounded to the frame. then again, my redtop is grounded "closest" to the alt because of the big 3, they share the same ground, so then again it probably would benefit.
