I'm installing the E-05 ACK ELT. With the cockpit dash remote plugged in to the audio alert strapped to the ELT, I get a low chattering/clicking tone and an ELT "ON" light constant flashing on the dash. Push and hold the ON or RESET button and the sound and led light goes off. Acts the same with or without the cables hooked up to the ELT. Batteries test good.
I'm not hooked up to aircraft power yet, could that be a cause. Leaving the ELT in off position to keep the black helicopters away
