I have dual screen SkyView Classic in my RV-9A. It was installed 4 years ago and has worked flawlessly until now. I added a Garmin GPS-175 about three years ago, and it also has worked flawlessly for the ~175 hours since then.
A few weeks ago, I noticed that the system reported "ADSB-IN OFFLINE" and that a 1A circuit breaker in my aircraft had popped. I reset the breaker and the ADSB-IN (SV-ADSB-472) came back online. All other systems continued to work properly. On another flight a few days later I got a similar message and this time apparently the 1A breaker had failed (resetting the breaker did nothing, and a continuity check on the ground confirmed this). Since then, until yesterday, I had flown without ADSB-IN and the 1A circuit breaker, and the rest of the SkyView components continued to function properly. ADBS-OUT continued to function properly (it's on my transponder circuit).
Yesterday I replaced the failed 1A with a new 3A breaker and it functioned fine for most of a 25-minute flight. Near the end of the flight I saw the new breaker pop and again received a warning ADSB-IN OFFLINE. Something else seems to be at play here. I’ve checked for any shorts at the wiring to/from the circuit breaker and have found none.
Aside from a thorough, painstaking connection-by-connection examination is there anything in particular that a likely source of the tripping? Is it possible that the SV-ADSB-472 component is failing (although it worked fine initially when the new breaker was installed)?
Insight welcome!
