power drain

What is your question?

I have a major power drain which kills the (new) battery after sitting for 2 or more days. I connected a test light to negative battery cable and the other end to the negative battery post, i then proceded to pull out every fuse and relay, no change. The alternator is good, I even disconnected the computer and their is still a draw. I'm rightly stumped. Any help would be appreciated thank you.
