Brief Description: Troubleshoot fuel pressure, test ELT
No pics today—nothing worth taking a pic of. I spent some time with the Dynon EFIS today. I believe I have traced the fuel pressure problem to an incorrect sensor. According to the part number stamped on the sensor, the range is 0 to 15 psi. The EFII boost pump I have installed is supposed to output a steady 30 psi. Most likely this is why the indicator on the EFIS screen goes off the scale and displays a red X. I’ll verify this with Dynon next week and get a replacement ordered. I also did a self test on the ELT per the manual. I used a handheld receiver and verified one second of 121.5 audio, followed by 1 beep—which indicates the system is functioning properly. I lightly sanded the leading edge of the right wing tip and then installed it.
