You are just Mad because sometimes the boxes Make Sparks Disappear.

On a more serious side the local speed shop here has a device they can test them with, however and see if they at least throw a spark.

Sometimes you have to just replace the box to know for sure. If it was not the box you at least have a spare going forward.

My son had one of the 6 series (I think) analog units. I swear in the MSD trailer you could have welded with the thing. Twice they said nothing was wrong with it. It had a slight high rpm miss. However you could replace the box and the miss would go away, put the box back in and the miss would return.
