Dan, you're giving me too much credit regarding "putting a lot of time into it"...I was only there for two hours. I had to leave early due to a line of thunderstorms that was about to force me to spend the night at your house. In those two hours, I properly set the timing (statically), and quickly declared the electronic ignition dead. I then ascertained that the spark was intermittent, and suspected the condensor because it was obviously arcing internally while testing (I could hear it from three feet away). I bypassed the coil joiner just in case (your phone message said it was bad, but I'm not sure that it is...doesn't jive with testing, and is comprised of two big diodes that are "polarity sensitive"). Given that we didn't have time to get a new condensor, and I didn't bring one with me (I meant to), I had to leave before the condensor was swapped out. But since you swapped out the condensor AND the reversed polarity on the coil (which you assured me was correct) at the same time, I didn't pursue it, knowing that reversing polarity on the coil may slightly affect the high RPM performance and the overall life of the plugs, but will work fine under all but extreme use. If the coils were wired in reverse, that explains the fried electronic Crane module. One nanosecond of reversed connection will fry it. For those who are wondering, the red stripe goes to the positive side of the coil, the yellow striped one goes to the negative. What I'm trying to say is that your "divine intervention" may have flown in with "N56ML" on the tail! See the top of http://www.n56ml.com/sunsets/ for a view of the weather on the way out of KCUB...
