CUDA DIED...NO SPARK to PLUGS !!

Just plugged in a new blue box.........Still no spark at all.

Next I'm poppin' in a new ballast resistor, then a new ignition switch (which is original)......

(I'm not just throwin' money at it.....I really want extra parts on hand since this is my personal cruiser.......I might get lucky changin' these out one at a time and find the problem.....I don't want to monkey with the dash unless I have to).
