The biggest problem with MSD boxes is the person that installed it, Most just put a screw in the painted sheet metal for the ground wire. Screw loosens up over time and the box looses ground. Dam MSD box, engine misses and sometimes doesn't run.
it's ok to butt heads, just don't do it with a butthead

Mine has a light on it that blinks or turns on when it is powered up.. I think you touch the white wire to ground and should see spark. Kevin

I had my MSD box go dead as I mounted it upside down above my glovebox liner on my 70 Charger...damn thing would always buzz too...
There is a shortcut to do ...ask on MSD forums....you short two of the wires and listen for an arc...if you have an arc...you have a good MSD box. Have you checked to make sure the black cable is on a good ground and if your 16ga red wire is actually making contact with keyed 12v?

I know some have trouble reading, but MSD has blanketed the Web with wiring diagrams. There is no excuse for having an improperly wired MSD. Well, if you are blind and working alone, then yes there is an excuse. Otherwise, no excuses.
Sounds harsh, but really? There are only six wires, five if you run points. Two to the battery, two to the coil, two to the electronic pickup or one to the points. That's it. The box is grounded by connecting the fat black wire to the battery. DUH!
The procedure for testing is likewise all over the Web. Using the white wire is the easiest for me.

Any idea on what went wonky in the dist? Does the pickup have continuity? generates ~1 AC volt when cranking?. I'm assuming the gap was still good.
