zxsonnyxz Posted October 9, 2011 Report Share Posted October 9, 2011 Not a 100% sure what you mean by that, but basicly you're using the chassis of the car as a negative conductor between front and rear so solid metal-to-metal connections both in the front AND rear is needed. All the power running through your positive power wire from the front batt and alternator is also going through the negative wires and chassis.

1988JimmyRE Posted October 9, 2011 Report Share Posted October 9, 2011 You don't have to ground a battery to another battery, Your first battery needs lets say 2 good grounds one to the frame one to the body Your Second battery needs one to frame one to body as well Then do an Engine to frame Then a Body to Engine Something like that should work fine. Remember to sand ALL grounding locations, i always overkill my ground and do Several.

zxsonnyxz Posted October 9, 2011 Report Share Posted October 9, 2011 You can ground your batteries seperately, and for the power wire you'll be fine either way with your setup. I think most people run it from the battery as its often the easiest. Do whatever you feel like, just don't forget to fuse your wires.

1988JimmyRE Posted October 10, 2011 Report Share Posted October 10, 2011 All Positives on the batteries ran together and fused, your amp positive off the 2nd battery and fused negatives need to be grounded like i said before you need one wire from alternator to battery too. and no you don't need to ground a battery to another battery BUILD LOG-->1988 S15 Jimmy V8 4x4 2 15" RE Audio<--BUILD LOG Link to comment Share on other sites More sharing options...
