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 

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 


 

Dear team During aircraft power up I noticed ELT buzzer sound in the tail cone so I checked ELT  for activation but it is not activated (No LED indication ) on external remote switch and ELT  So we turned off the battery and buzzer Sound stop   Now again power up aircraft so now I access the ELT and disconnect molex connector on ELT and buzzer sound stop 
Now remove the ELT and refer Aircraft wiring manual  buzzer power is provide by ELT Now we check voltage on ELT on PIN NO. 2&4 showing 12 VDC
First thing is clear ELT is Faulty 
Now second thing is why buzzer is activate during aircraft power on
Aircraft only provide 28 VDC for remote switch LED (on indication)  
 
 

Dear sir 
Stormscope is not being shown on Both PFD and MFD 
Model-Stormscope series 2
WX-1000E
PN- 780-8060-6086-5

 on stormscope Processor Fault LED there is no fault 
we check the wiring from PN387 to Displays found ok 
and PN837 to PN342 found ok 
and stormscope processor is also change with new one       
please guide us for  next step 



 

Dear Sir
Yes nav tuning is from Garmin GNS 530 only
i think ARINC Adapter KDA-689 is only for Show information to Both PFD 
we also check wiring 18,19,20,22 of both GNS 530 found good
 
and these 3 splices behind of backshell of KDI-574 i also checked splices its in good condition
yes we dissconnect GNS1 and check with GNS 2 sometimes its work or sometimes not (intermitent condition)

when i  powered the aircraft on in morning for first 10 mintue DME working fine from both NAV selections 
but after that DME from NAV 1 stop working 
now we suspecting the GNS 530 and KDI 574 
maybe we will get GNS 530 and KDI 574 for testing in few  days.
 

      Sir KDA-689 is use for showing information (distance) on both PFD 
KDA take data and convert it to ARINIC 429 and share it with IAPS( integrated avionics Processing system ) it contains various types of LRM ( Line Replacble module) like 1. Power ,FMC , IOC, CSU ,FGC) 
Aircraft Avionics from ROCKWELL Collins Pro line 21 and radio from GARMIN
 
VOR/ ILS. frequency Working fine only problem with DME

We also check system while KDA-689 connector unplug  but Same problem exists

is there any way to bypass the nose junction box PN333
