JesseyMclame Posted October 24, 2013 Report Share Posted October 24, 2013 Ok so I get voltage drop on my secondary battery bank, but virtually none at all in my front battery. All my equip is in sig. So I was wondering, would it help any more to just attach the power wire in front that's going to my front bat to rear batts, straight to the alternator instead ?

Karkov Posted October 24, 2013 Report Share Posted October 24, 2013 Well, the alt is gonna charge the front battery first because it is closer and takes the path of least resistance but it will still charge the back so fast you will never notice if you were to hook the rear batt stright to the alt as well. Not sure if you are using CCA or OFC, or how long yours run(s) are, or how many runs of power wire. What if you just added an additional run of power wire from front batt to rear batt? Also, are all connections tight? All grounds are good grounds? How much is the voltage drop you are talking about?? There *may* be some from front to back but there really shouldn't be IMO, I mean checking the front batt voltage and the rear batt voltage at the same time and seeing a difference.

What voltage does your vehicle idle at? how about under full tilt @front batt? @rear batt? I'm using CCA, and the 1 run is probably like 14-16 ft ? And how would it benefit another run from front to rear batts? All connections are soldered and completely solid, and all the grounds are tight and shiny metal. And i'm dropping about 11.8-12v on the rear battery bank and like 13.8 in front at full tilt. my voltage idles at like 14.1 up front, and 13.8 rear.

ToNasty Posted October 24, 2013 Report Share Posted October 24, 2013 id do 1 more run just for the hell of it. did you check the rear batteries? if there going to shit? ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
HHR Ed Posted October 24, 2013 Report Share Posted October 24, 2013 Check the rear batts to make sure they are OK. Run another power wire from front to back batts. Run a second ground from back batts to ground. Run ground wire from alternator chassis to ground.

Run ground wire from alternator chassis to ground. ok rear batts are fine, then how would i add another ground ? just same terminal on the battery that's already grounded, and ground that to chassis as well ?

Yep, or you can ground to the terminal of the other batt. It wont really matter.
