I trust that Chapter 30 will follow? -- Ian -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net]On Behalf Of John Slade Sent: Saturday, June 04, 2005 3:41 PM To: Rotary motors in aircraft Subject: [FlyRotary] EC2 problems - solved 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! John Just guessing, but maybe the new EC2 can't communicate with a pre-autotune EM2 like Buly's. ?? 3
