Checking a MSD box to see if it's bad?

[80proZ]

I believe my 6AL box took a crap, but i want to make sure before i get another one.Is there any way to test it to see if it's bad.I have an entire MSD ignition(pro billet Dis,blaster coil and box).I'm not getting power at the coil but i got power everywhere else.The coil is good,But shouldn't you have power from the two wires that connect the coil to the box?Any help is greatly appriciated.

I've only checked them with the ignition tester. I could loan it to you if you promise to send it back!
