My car currently has an MSD box and Im about certain it has gone bad. The car will sometimes cut out, and the only diagnosis Ive found is that it stops sparking. Ive checked and found spark to enter the box but none leaving it.

What must be done to disconnect the box and simply run the ignition without it. MSD says send them the box and they'll check it out and replace if it cant be repaired. But this is my daily driver so how can I bypass for the time being.

Any help is appreciated, thanks.

 

Find MSD's install procedure, then do it backwards to un-install the box?
