Good & Bad news Chris. Got the EC2 and have repaired its EFI functions. It had it's brains scrambled pretty good but the bad news is that it was able to talk to an EM2 just fine (even before the EFI repair). The bad news about open grounds are that they are an equal opportunity destroyer. Assuming that the serial and other wiring is intact, the NOP message on the EM2 meant that the problem was that the EM2 had gone deaf on the serial bus, not that the EC2 had gone mute. Whenever the NOP message appears on the EM2/3, both EC2 & EM2 should be sent in because it is impossible to tell which end has the problem without checking the serial bus with an O-scope.
I'll send the EC2 back today and it should run OK but if you still see the NOP message, the EM2 will probably need some TLC as well.

Sorry to side track the T-shirt discussion. I think we need something more distinctive though to call more attention. Something "cute" but potent to deliver more of a total message. Just a thought.
Anyway, Tracy should have my EC2 by now. Hopefully he is not overwhelmed with work and I will be back with a running engine soon.
Concerned with my broken ground wire, I examined where the wire broke, right at the connection. I crimped some test wire with the same wire, terminators and crimps and what I have determined is that I MUST have crimped the 16 gage wire with the wrong size crimp (20gage crimp) and the smaller size crimp cut the the thicker wire to a point of failure. The test crimps I did with the smaller crimps on the larger wire produced the same visual result as what failed. I have done so many crimps of 20 gage wire, I am guessen' that my motor memory just went to the red crimp. <embarrassed sigh>.
Just a small data point.
All the best,
Chris
