Hello all,
I have a friend with a new to him RV9A that we are having some problems with.
EFIS-D100, EMS-D120, Garmin GTR225, Garmin GTX345, and Dynon AP74.
Every once in a while the 2 dynon screens will just go black. The D100 has a battery back up and the battery back up does not activate or keep the unit running. The failures have happened more frequently lately and now correlate with the push to talk being activated (screen go black when PTT is pushed). Cannot duplicate the problem on the ground and still very intermittent. The screens are powered by separate circuit breaker style switches and obvious defects of grounding have been looked at.
One time the screens came right back up when cycling the switches, but on another occasion cycling the switches did nothing.
Any ideas? Thank you all.
