[QUOTE="ahole-ic, post: 6681979, member: 619324"] With all due respect, if you gained .2 to .3 volts by making a long run to the back, then you did not do the big 3 and your rear ground correctly. I'm not trying to argue, but with no current being drawn and going through welds and pot metal, you'd still read a dead short. It's under a heavy load where the resistance rears its ugly head. In my particular case, I'm on the same beam of my frame. It is very thick steel and I'm connected to it up front and in the back. It's like I'm directly connected to the alternator. I realize not everyone has that luxury, but if you take the time to investigate your grounding path and make good solid and short connections you will in almost every case have less resistance than several 1/0 runs of copper. If you're lazy and just want to throw another run of 1/0 in there, sure that might work but it's almost never necessary or as good as if you took your time and grounded to your frame correctly.
