What happened?
I'm going out on a limb...DDM is known for this. They reverse polarity on connections. You could carefully try to find out if that's the prob. Unfortunately, I don't recall which connection is usually the culprit.
Fiddle with one and see if you can get it to fire. If so, problem solved, just repeat it on the others.
