Decaf Posted September 25, 2011 Report Share Posted September 25, 2011 there was ZERO change when i switched between my strut tower bolt ground and front to back ground (both 2/0)... depends on vehicle i would assume Quote Link to comment Share on other sites More sharing options...
LoudNLow931 Posted September 25, 2011 Report Share Posted September 25, 2011 I saw a substantial increase in both my charging voltage (rose from 13.6 to 13.9) and a more constant voltage under load by grounding directly to my battery versus the seat belt bolt I was using before that... So I'd suggest grounding to the battery But where are your batteries grounded?

AA98hoe Posted September 25, 2011 Report Share Posted September 25, 2011 (edited) I think everycar has body bushings lol that's how the body is mounted to frame. I think the op has a power wire issue not a grounding issue. I have 10 rus of 0g front to back 3 alts and 6 batterys 2 in front 4 in back. I have both frame grounds and neg runs from alternator bracket. Do you know why mechman adds a grounding stud to there alt case? Cause the back half of alternator is the negative part and of course the post is positive. Most alts just use the mounting bolts as the neg point which in turn goes through engine block through factory ground wire to frame and or battery negative side. That's why big 3 helps because factory ground wire or strap is in sufficient also factory charge wire Edited September 25, 2011 by dc98hoe Quote TEAM DC AUDIO VEHICLE:98 chevy tahoe 2wd 3-4 drop HEADUNIT:alpine 9886 PREAMP:arcaudio FRONT STAGE:4-6 1/2s selinium,DD component set and 4-selinium tweeters in each door KICKPANELS:jl audio 5 1/4 REAR DOORS: dd components 6 1/2s HIGHS AMPS:zapco 750.2 on front doors,zapco an another 750.2 on kicks and rear doors SUBS:4-ascendant audio 18s with 5 spiders in a custom box built by KINGSUV SUB AMP: 2-dc7.5s ALTERNATORS: 3-mechmans 1- 425comp, 1-smd spec350, 1-270 with adj voltage harness on custom dc bracket WIRE:10-runs 0g front to back BATTERIES:6-d1400s TL results:157.1 at 38hz and 156.8 at headrest score @37hz.
