    Are you sure you checked the check engine light correctly, what happens after the reset procedure?
    Are you sure you didn't just leave the short connector in the thing, If you leave it in it will just stay on.
    It would also help to know what year make model swap etc.

    just do one or the other, either disconnect the battery, OR remove the 7.5amp backup fuse located under the hood, I always just unhook the battery that way I know, you have to leave it unhooked for a few minutes.
    Just make sure that the thing that you plug in to check the codes is NOT plugged in, otherwise the check engine light will stay on.
