Low battery indication is provided by 7 flash on LED so its not Battey low
PT514 is ELT/Nav interface unit its providing GPS data to ELT
5 volt is not for charging but I don know what it is for
Yes sir ELT is faulty
But second thing is why buzzer only sound when we turn on aircraft battery
as per wiring diagram Buzzer power is provided by ELT then buzzer should always be on even if we turn off the battery
Sir what do you think about it
We are not getting tone on 121.5 MHz
We any getting only buzzer sound
buzzer only sound when we Turn on aircraft battery and when we turn off aircraft battery buzzer will stop
we are unable to reset
Sir we did not hit the ELT Actually aircraft in Hanger for maintenance so during aircraft power on I noticed sound was coming from the buzzer
G-switch is not active and ELT Is also not active but buzzer sound comes only when we power up the aircraft
Buzzer power is provide by ELT but why its turn on while power up the aircraft
