HELP, please! Finding a battery drain.

Ok, I am still trying to find what is causing my battery to drain. I replaced the battery with a brand new one and it was drained dead within 2 days. Here is what I have done so far.

1.) Used "metal blade test" to check altenator and see if it magnetizes. I didnt feel any type of pull but maybe I was doing it wrong.

2.) Then I jumped the truch, removed the jumper cables and then disconnected the truck battery leads and the truck still ran with just the altenator. I believe this tells me my altenator is good wether it passed the first test or not?

3.) Someone suggested I disconnect the negative battery lead from the battery and place a 12v light between the negetive lead and mattery terminal. If I had a draw on the battery with the key in the off position it would show up. The light came on when I did this, so this means without any doubt I have something drawing the battery down when the key is not on?

4.) Then the 2nd part to the number (3) was to remove the fuses from the fuse box one at a time untill the light went out, then I would have found my faulty area and then be able to pin point where to look to find the draw. Well the only problem is I removed the fuses one at a time (3 times) and the light never went out. I even switched in a multimeter on the last time and watched the 12vdc stay perfectly constent, never faltered.

*HELP PART* So what do I do now? Does this mean that the draw on the battery is somewhere between the battery and fuse box? Is this the only option I have? Do I follow the battery leads to the fuse box? Am I missing something obvious? Attached is a picture of my fuse box, I doubt it will help but thought It wouldnt hurt.
