I have the Garmin 328 Transponder in my R44. Does anyone know where the altitude encoder is located? My transponder shows the altitude in the 328 display on the ground but when I start to fly it goes blank. I am hoping just a loose wire and want to know where to look.

Should be behind passenger seat back on left hand side of aircraft.

It was and thank you. To get the seat back off you must unscrew the plate that holds the seat back about 10 screws.
