Default Computer resetting after battery relocation

I've relocated my battery (new red top) to the spare tire well. When I start the car the computer resets every time. This has become a pain in the a**. I ran 1/0 to the starter from the battery from there I ran #1 or 2 and tied in to the existing red hot wire. This wire used to go directly to the battery in it's original location. I also ran a new #4 from the alt.to charge the system. The battery is new,wiring connections are tight. Oh, the neg is run from the battery to the roll bar in the rear hatch area. Any body have any ideas? Do I need to run the neg. to the block. I'm thinking the starter may have a bad winding or short to ground.(orignal 75K miles).

I bet your ground is not good enough. I had this discussion before, and the general consensus is that the more grounding you have the better. Try running a ground wire from the computer's ground right to the battery ground, and also tie the block to the car with a good heavy ground strap.

Probably will solve our problems I bet.

It was a voltage drop problem. I ran another hot to the term. I made this connection to the orginal factory red battery wire. My mistake was running the large 1/0 cable to the starter then jumping up to power the rest of the car. So basically I ran a #8 from the battery to the cars original power term.
