This weekend I moved the battery to the trunk. I used the kit that I got from Summit and after about 5 hours I was done. I try to start the car and it turned slower than usual but started. I went around the neighborhood and came back. I was also testing the new Detroit Locker I put in. I came back, parked it and went back in the house. Later I decided to take it for another spin and came back. I accidentally let go of the clutch before turning it off(I was really tired). It turned off on me. When I tried to restart it, it wouldn't start. I checked the battery and it had 12.3 volts in it. After draining it I decided I would leave it alone and figure it out. I used 2 gauge battery cables that came with the kit for the battery to relay and battery to kill switch, but since I didn’t have any more I used a 4 gauge cable from the switch to ground which I put the truck floor. After reading the article in the archive I am thinking I have this problem because of the ground, but what could be the problem? Should I bolt the ground cable to the frame rail?
