Short? Alternator? Ground?

[Mholme3 at aol.com]

4kq with brand new battery.  Doesn't get more than 10 volts and sputters on acceleration.  It will not move with any consumers(headlights, radio, etc.) going.  Warning lights on dash are glowing very faintly.  Start testing for shorts with test light through battery ground and start yanking fuses.  Pulled all fuses one by one, test light stays on.  Pulled all relays, test light stays on.  Start yanking harness at back of fuse box.  Pulled yellow 5 wire harness near rear of fuse box, test light goes off.  I assume this is the source of the problem.  But the battery/brake/oxs light are still glowing with this harness pulled and the key in the "on" position.  I'm at a total loss here.  I have checked all the grounds in car and under hood. Cleaned all terminals on battery and alternator.  Could this be my alternator  saying bye bye?  Internal short in fuse box? I went through this two days ago and the car magicaly cured itself and was fine for a day.  Any help is appreciated.
