MSD 6al2 Box SHOCKED ME!!!

Ok, now that I got your attention, so far, I am not having luck with MSD products in general, (I WONT RANT). Anyways, just wired up my 6al2 box. Wired as per instructions. Got my switched 12 by removing ballast, tieing Brown and Blue wire together...So, I went to start the car, while i started it, I was HOLDING the box, to verify the light was on. IT SHOCKED the hell outta me, but the car did run, ran good. I could then touch it and it didnt shock me. At this point the box was just laying on the carpet under the dash, I decided to MOUNT it on the passenger side kickpannel. Got it mounted...NO SPARK or start. Took it back down, set it on the carpet...started rite up. Basically, anytime the box touches metal, it like grounds out and wont work. Any ideas? Another bad MSD box?
