Battery Help???

im just wondering if there was a sticky on here on how to wire 2 or 3 batteries in a car. do i just run pos to pos from the front battery to the rear batt and the pos to pos from one rear batt to the next? just trying to get some help before i install all my stuff again. i just got the 2006 2500d //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif .

Yep, thats all you need to do. Ground the rear batts together (either link them together and ground one or ground them at the same point at the rear) and then one to chassis for the the main batt so all batteries have the same gauge power/ground cable

if you can do the same with the grounds

if you can, do the same with the grounds

No need to run a ground from front to back - unless you are a wire salesman........hmmm, maybe I should switch my position on that topic....//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif lol

in a large set up with larger batteries WE always recommend doing that. some people argue they dont but we never have a performance issue when people wire it this way and use the correct size of battery. now im not saying it cant work with/from a different ground but some grounds are better than others....full parallel connection in alot of cases takes away from potential problems. if you arent running a relay/isolator it wouldnt be a bad idea.
