Tach sensor issue - G3X
I have an RV-6 with Garmin's G3X in the panel. My tach sensor is the type that screws into the vent hole on my mag (Bendix, in my case).
Recently, every time I start up cold, my tach reads zero. The first time it happened I played with different RPM's and fiddled, and finally concluded it wasn't working and was about to shut down, when it instantly came on-line. I went for a flight and it was rock solid reading from taxi to shutdown. It seems to do this every time I start now. Delay of a minute or so, then reads solidly. In one hot start after refuelling, it read instantly upon startup.
