Tribe Called Bass Posted March 6, 2019 Report Share Posted March 6, 2019 So at the moment I want to add a D3100 battery to my 2nd battety tray in my 2015 chevy silverado with my stock battery(temporary) Questions; -will i have any problems connecting the two batteries together? I think the factory battery is AGM -Do i run one positive wire from stock to the d3100? -Can i run a second wire off the d3100 to the alternator? Or should i keep it only connected to the stock one?

RickyFriery97 Posted March 7, 2019 Report Share Posted March 7, 2019 i ran a similar setup in my old 2007 tahoe. i had a D3400 in the secondary tray. i did not have the battery tied directly together. positive lead of the alt, then grounded to the frame, or alt mount cant remember. im not sure whats different on these newer trucks 2014 Chevy Silverado Crewcab 1994 Chevy Full Size blazer Link to comment Share on other sites More sharing options...
ToNasty Posted March 7, 2019 Report Share Posted March 7, 2019 Posative run and a negative run. Just dont ground the secondary battery to anything but the oem battery or youll get a high charge ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
