Tracy and
others.
Following more than 12 months of battling with EC2 issues I'm
pretty sure it's Eureka day!
After
rewiring and testing for almost 4 weeks I plugged the EC2 in last night, and got
exactly the same symptoms as before. NOP flashing indicating no communication. I
took the EC2 to Buly's plane and tried it in his installation. Same NOP, so I
was thinking I'd fried it again. Before sending it back yet again I decided to
install it my plane one more time and see if there was a spark.
To my
amazement it worked. No NOP, and I could bring up the EC2 data. The only thing
that changed overnight was that I moved the cable to unplug it. I climbed in the
back and found that I could make the NOP flash, or stop flashing, by moving the
cable. I haven't taken the connector apart yet, but I'm expecting to find a
broken wire inside the insulation, probably near a solder joint at the pin.
Whenever I bent the connector outward for testing it made contact. When I
bent it back to plug it in, contact was lost.
Bingo!

Just guessing, but maybe the new EC2 can't
communicate with a pre-autotune EM2 like Buly's.
