Hi, I could use some help from all Garmin GNX375 experts. I have one installed in an RV-8 that has been working fine until a month ago the ADSB out stopped working. I get the code “ADS-B out fault. Pressure attitude source inoperable or connection lost.”
The plane is new to me and the wiring diagrams are sketchy. It has two GRT HX Horizon EFIS’s in the panel which may be the source for the pressure altitude. Don’t know. Very hard to trace out. Thoughts?
Thanks in advance
