95 south Posted June 30, 2013 Report Share Posted June 30, 2013 I know it may be a stupid question but with a 270 amp alt and 2 runs positive/ 2 runs ground to the rear should I do 2 runs of 0 gauge wire from the alt to the battery?

tacomaguy1 Posted June 30, 2013 Report Share Posted June 30, 2013 One from alt to front battery is sufficient One run will carry the 270a from the alt just fine Team Flex Issues Link to comment Share on other sites More sharing options...

95 south Posted July 1, 2013 Author Report Share Posted July 1, 2013 That's the problem. Where am I grounding the other 2 wires? The side frame of my SUV is not good and I don't know where to ground the engine? Its driving me nuts because it seems no matter how much wire I run my voltage drops fast due to poor grounding up front.

Tarball Posted July 1, 2013 Report Share Posted July 1, 2013 Ground your battery and your block to the same spot. Ideal spot is a thick heavy metal part of the frame. Take some pics of your engine bay.

fecupe2001 Posted July 6, 2013 Report Share Posted July 6, 2013 depends on the resistance, but let me tell you, we added 2 more extra runs from alt to battery, now my teammate has 2 pos and 2 neg from alt to battery and did a BIG difference Big3? not bad, i always recommend doing at least the big4, same big3 but adding a run from alt to battery, that helps a lot , specially when you have an aftermarket HO alternator I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.
