Thread: Adsb unit light

  1. #1

    Adsb unit light

    I have the 74112 afs adsb unit, there is an LED next to the input plug, when does that led come on? Is it an indicator that everything is working or only when receiving data? I have power, ground, tx, rx connected properly, the loop back test to efis works ok when p 2,3 jumpered together. Is there something wrong with this receiver? Not flying yet but wondering about normal operation indications.

    Found the problem, low battery voltage.
