did you actually read the big 3 thread??? because if you did.. you would know that alt negative is NOT one of the steps. You should go read it again to see if you messed anything else up.

alt negative?

there is no alt negative. the alt is grounded via the engine. so unless you were using an alt ground->chassis instead of engine ground->chassis, that's ok.
