Posted March 9, 201411 yr Why do people run two runs of 0 gauge negative when they do runs of positive can't I just ground it in the back off my second battery
March 9, 201411 yr Why do people run two runs of 0 gauge negative when they do runs of positive can't I just ground it in the back off my second battery To decrease resistance from the front battery (connected to alternator) to the rear battery(s).
March 9, 201411 yr Its all connected to the frame. Some people go the extra mile and run the same amount of positive and negative runs (more so in competition) from front to back but neither way is wrong really.
March 9, 201411 yr If it is a full frame car/truck, the negative runs are not needed if you bond to the frame correctly. In fact, you can easily raise overall series resistance when running a separate ground instead of properly using the frame. In a unibody vehicle there may be gains from running an additional ground.
