That is why I programmed the EM2 to display "NOP" (inoperative). If the the wires are hooked up properly, power is on to both units and the EM2/3 flashes "NOP", the data link is blown. No EE degree required : ) BTW, if I read your previous post correctly, you tried to crimp a 16 ga wire on that tiny subminiature D connector pin. The maximum wire size is 20ga and the recommended wire size is 22 ga. A 16 ga wire will almost guarantee a failed crimp connection. The short 16 ga wire connection recommended in the installation guide goes from the *Ground stud *on the EC2 case to the airframe.

=A0If the serial data link between the EC2 and EM2 is blown (by a miss= ing ground or other reason) as indicated by the NOP flashing in the EM2=A0 = TACH window, it means that the EM2 and EC2 can no longer communicate each o= ther.
