My first post to this great forum...
Resurrecting this old thread because I have encountered the "cycles on and off" issue, and wonder what the outcome was for the original poster.
Mine is a new D10A install, complete with the internal battery, remote compass, OAT, and Dynon GPS. Everything seemed to connect and play well. After installing, I taxied to the compass rose to calibrate the EDC-D10A. While navigating the menus, the unit powered off, and then back on, then off, etc. So, taxied back to the hangar.
In the hangar, I double checked what I could, and turned on the master to power on the unit. After a few minutes, it powered off and on again, as before. I turned off the master and the unit remained dark. I powered it on with the "On" button so it was getting power only from the internal battery (Master switch remained off.) And again, within a few seconds, it powered off, on, etc.
My thought was it may be overheating. So, I reduced the screen brightness (it had been set to maximum brightness.) With the reduced brightness, it appeared to behave, and stayed powered up. But I have tested this very little.
This doesn't appear to be a very common problem, from what I can tell...
Any updates on this issue?
Thanks,
Peter
