The failure modes of the P3 and indications are a bit of a mystery. However, I did bite the bullet and wired in the Flight Data Systems L2E and the LED outputs from each P3 box to my Garmin G3X Touch/GEA24/GAD27. With this configuration, I can monitor (not control) the timing of each P3 (as reported by the P3) on the Garmin G3X Touch. If power is lost to either of the P3's I also see a message on the CAS and hear an alert.
