Why are my distributor cap terminals burnt?

I popped the cap off my distributor this morning to install the FBO limiter plate, and upon inspection, found the terminals to have a "burnt" appearance. The distributor is a new Summit Racing electronic distributor, running an MSD Blaster 2 coil, blue ECU. About 100 miles on all. Engine is a mild 440 set at 22 initial (plan on adjusting the timing).

Am I running the wrong coil?
