    Well, I see the cracks in the potting, which may or may not indicate a problem…I don’t see any indications or arcing though. Wipe off the coils, and have a close look all over the coils for signs of arcing. Did the coils check out OK on the ohm meter? How did the primary connections look? How about the plug leads/boots/terminals, did they seem OK?
