When you did the Big 3 upgrade, did you also upgrade the battery to body ground, and the body to chassis, and the chassis to engine? I know my Dodge had a weird battery to body ground.
Toby Ratcliffe Posted April 6, 2012 Report Posted April 6, 2012 And why 3 screws, and not one big bolt?
Banshee421 Posted April 6, 2012 Author Report Posted April 6, 2012 No big 3 never drop below 13.7 so did not think it wias needed
Guest Posted April 6, 2012 Report Posted April 6, 2012 body ground? sounds like a shit ground to me, in my opinion. you need to have it on a thick piece of metal like the strut tower or the frame itself, like i stated earlier like twice. where was this 13.7 measured. at the amp itself? or on a stock volt meter in the dash? the big 3 is always recommended to do. regardless of voltage drop. i saw a full .5v increase doing mine.
