Brief Description: SL30 testing - transponder ant - bu batt wiring
Drilled hole in airframe and installed TED transponder antenna. Cable not yet connected. Dr. Lori Alvarez assisted in this.
Dick Isherwood and I attempted to get the SL30 working without success. We tried testing in both on the bench and in the airplane. We could not get the com side to receive.
I identified the aux 6 input of the EIS as being a gray wire with a red strip. I ran that wire down to connect it to the back up battery charge state sensor wire from the backup battery. I was unable to connect them even on my stomach in the airframe because of the awkwardness of the connection. I tried twice to squeeze a butt splice connector without success. I did not have a plug connector available. I will get some tomorrow at Skycraft.
I put pins on the shield and the two wires from the 396 audio cable to the audio panel. The white wire with the blue stripe is the tip, which transmits the left channel and attaches to pin 23 on the J2 connector of the PMA audio panel. The white wire is the ring connection on the plug, transmits the right channel, and connected to pin 24 of the J2 connector. The shield is the sleeve on the plug, and is connected to pin 25 on the J2 connector which is ground.
We tested the Garmin 396 and determined that the audio from it was being received. By the time we got to this point the voltage had dropped so much that the audio panel was not working. The audio signal from the 396 was heared in the headset although at low volume.
