msd 6al no spark at plugs

Ok In have a 340 that I am using a msd 6al box, msd 8534 distributor and msd blaster 2 coil. I currently have it on a run stand to do my initial break in but I have no spark to the plugs. I have checked the box by jumping the leads per the msd trouble shooting instructions with a new coil and I did have spark coming out of the coil wire. I currently have it set up with a 20 amp toggle switch wired to the battery and then wired to a push button for the starter. The wire for the box that is to hook into the ignition is also hooked to the out side of the toggle switch that connects to the push button. So what am I missing here should I run a direct wire with some sort of shut off directly from the battery to the ignition wire to insure that I have a constant 12 volts or what. Any help will be deeply appreciated. As a side note I have it wired just like the instructions show.
