Original poster: "Robert Hanford" <pomnept-at-comcast-dot-net> Thanks Terry, I'm running a 15k 60ma (supposedly 70-75ma w/ some shunts removed) NST with a .011 MMC. Could you clarify what you mean when you say "the coil could be trying to go over voltage?" I will check my wiring thoroughly tomorrow.Thanks for answering my newbie (kind of ) questions. Rob
