Does this problem occur with engine running or even with engine off? If the engine is running, have you tried shutting off the alternator? If the engine is not running, are you on a ground power source? If so, what happens running on aircraft battery alone with the ground power source disconnected?
Please email sys and data logs to support@advanced-flight-systems.com

Jonathon, thanks for the speedy reply. I will capture the sys/data logs soon and email them to you.Originally Posted by Jonathon
The problem occurs both with the engine running and engine off (just the panel powered).
With the engine running, yes I have shut off the alternator - no affect other than voltage dropping from 14.5 to ~13. Erratic readings will commence (or continue).
Without the engine running, I have powered the panel many times with just the ship's battery (~12.5V) and many times with the ship's battery on a charger (13-13.5); no difference. Either way the erratic behavior begins sometime after 5 minutes (colder seems to equate to longer, up to 40 minutes).
Once I accidentally left the master switch on overnight (with a trickle charger which couldn't keep up). The next morning I expected erratic readings - but no, readings were steady and accurate! Voltage was down to around 11.7 so this made me think the 'cut-off' voltage for this behavior is somewhere in the upper 11s. (assuming voltage is the factor causing the problem...). -KJ
