Dynon Skyview Classic, ADAHRS Module

[skippydiesel]

Having a bad trot with my ADAHRS. Wondering if anyone else in Au experiencing similar.

 

Original (first) module worked perfectly for aproximately 130 hrs
Failed without warning, on ground, on pre engine start check.

Cable continuity checked and found to be good.
Loan module worked perfectly for about 5 hrs - Replaced, still working, when new (not remanufactured) module arrived.

No explanation from Dynon as to reason for OM failure.
New module had initial problems (frozen compass) - Fixed by belated download/update
New module worked faultlessly for about 4 hrs
New module failed on ground, on pre engine start check. 
Dynon sending a loaner module, hope to install today

Note:
First module failure , turned whole electrical system off several times - red cross & failure message appeared each time

Second module failure, as above, however each time normal screen appears but only remains for about 30 seconds, before reverting to red cross & failure message. 😈

Might be worth chatting to David Brown in Brisbane.

What's the failure message? That "Multiple Sensors failed" type thing can often be caused by attempting to do a pitot-static check without being in test mode, the ADAHRS sees the rapid climb/descent and IAS changes without corresponding GPS position or accelerometer changes and cries foul. Doesn't sound like you've actually done a P-S test, but it might be somewhere to start. First thing I'd do is unplug your GPS antenna, do a network calibration to rediscover all the modules but without the GPS, cycle power and see what happens.

Had a great chat with David Brown - certainly knows his Dynon (& other) systems inside out.😈

Latest ADAHRS fitted - off to the airfield to do the compass calibrations.
