christamez80 Posted May 14, 2012 Report Share Posted May 14, 2012 I installed a second battery. Before i installed it the meter would read 14.1 or no less than 13.5 but as soon as i connected the second battery it dropped to 12.3 and wont go higher than 13.3. Wut could be the problem?

christamez80 Posted May 14, 2012 Author Report Share Posted May 14, 2012 I ran a 0 gauge wire from the battery up front to the battery in the back and grounded the back battery to the body. Its in a tahoe. Quote Link to comment Share on other sites More sharing options...
Team_DC-Derrick Posted May 14, 2012 Report Share Posted May 14, 2012 sounds like a really bad ground to me, did you sand it down to bare metal? try a different location?

Nightshade Posted May 14, 2012 Report Share Posted May 14, 2012 The new battery that you installed may have a bad cell in it. Try testing the second battery by itself and see what kind of readings that you get.

Keith77 Posted May 14, 2012 Report Share Posted May 14, 2012 I would move your rear ground to the frame! Quote Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born. My penis is bigger than your penis I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle. Link to comment Share on other sites More sharing options...
