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
From the prints, it looks like you've got 5.6 volts present on ELT. I don't know if this is a charging voltage (if there is one) coming from the aircraft or if it starts at ELT.
I would think the aircraft is providing it.
Also..... without having access to the manuals, this might be a low ELT battery indication.
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
You’ve covered all the bases on the wiring checks.
Reading 429 data bus wires requires an adapter.
The RTX adapter was the cheapest I could find. It is a single channel “receive” only. Numerous manufacturers have their own software and adapters.
These usually have multiple transmit and receive channels. They’re not cheap. My RTX was about $800US.
Dear sir
we don’t have a data bus reader but I saw in your video that you taking ARINC live data
Using RTX Software can you tell me how to connect laptop to LRU Rack if I got RTX software
I have checked the wiring everything is ok and voltage is also coming on the antenna connector
there is nothing in the display Which tells us that data is coming we are not able to select stormscope on display
PN342 is IAPS( integrated avionics processing system) I think it’s taking some data from there ( heading )
We also checked for bad receivers. Like disconnect two and connect only one displays at a time and check for all one by one
Now we have doubt on antenna
During troubleshooting I check wire for 5 parameters
1. E- End to End
2. G- Ground
3. O - other ( connect for nearby wire )
4. S- shielding
5. I - Insulation
if anything other Then this pleases add
