I thought the box is triggered by ignition and sends spark to coil then coil energizes distubutor? The distributor feeds msd box?

a constant 12 volts is required all the time to keep the MSD box "alive". There are separate leads that go to the coil and separate leads to the distributor and a separate 12 volt "trigger" is needed to tell the box to "turn on" and do its thing.
