Dynon Sky View

Been wracking my brain (had to find it first) to come up with atopic that might just light a bit of a fire under this veeeeery slooooow Forum.

 

Please put on your best thinking/speciating hat.

 

Here goes:

The Story

 

The above warning came out of the blue. System shut down in full operating order one day -

 

Two days later turned on system, as part of prestart/fight checks, to check fuel levels (no other system on ) Screen warning as shown..

 

Air temps in high 30's, possibly even reached 40C.

 

Next day;

Removed ADAHRS from location aft of cockpit.

Plugged in short connecting lead SYTEM FIRED UP as its supposed to. 

Painstakingly checked each wire (x9) installed (long) lead for continuity - all good.

Plugged in installed lead - system works. FIXED????

 

Following morning

Intended to go fly - above warning came on even before engine start

 

Diagnosis (so far)

Contacted Dynon Au (Horsham Aviation Vic); Receptionist guessed system failed due to hot weather. Technician sounded doubtful and advised a System Diagnostic Down Load to be sent to Dynon USA.

Contacted Dynon USA, Technical - Problem common. When Units checked, no problems found💨.

Down Load sent.

USA (yet to analyse data) suggested RF (noise) interference from antenna (x2) COAX cables, running in parallel with ADAHRS connecting cable. 

USA requested ADAHRS be sent for examination - done!

Horsham sending loan unit .

 

What do the Brains Trust think - all speculation welcome😈

Can you get a supply voltage check before start, right at the unit using the ground right at the unit. That might conform poor power supply or earth connection. Does the device have an internal battery that might be dropping power when not used for a couple of days?
