Unhappy 12.75v draw on battery-can not find problem

I have done the following while troubleshooting:
  • Removed all fuses, relays, and diodes in both the fuse block next to the battery in the engine compartment and the fuse box at the left side of dash.
  • Unpluged ALL wire connections at the following areas - under the hood on all engine components - behind the left and right front kick panels - under the complete dash system - ignition switch - under both center consoles - and the brain box (computer) under the dash at the forward center console - and also unpluged the altenator.
  • I even removed the 60amp and 100amp fuses in the fuse box next to the battery.
  • NOTE 1 : then and only then will the 12.75v stop - now when I reinstall the 100amp fuse the draw comes back.
  • NOTE 2 : when I seperate the two wires at the positive battery post and only hook-up the main cable to the starter I do not get any voltage draw on the battery.
  • NOTE 3 : If I install only the secondary positive cable that goes to the 100amp fuse, and not the main cable going to the starter, the voltage draw comes back.
