Mark, You are right that the regulator has a connection to the Skyview.
But evidently there is a failure mode where the regulator has failed but tells the Skyview that it is OK.
I installed a John Deere AM101406 four years ago and it has not failed yet.
I mounted it with heat conductive paste and a shroud with air blast tube to keep it cool.
I also attached a thermocouple to it to monitor the temperature which gets up to about 150 degrees F
after takeoff when the battery is recharging. In cruise the regulator temperature drops to 130 - 135F.
The John Deere AM101406 is available on eBay for $19 with free shipping. I bought a spare one but haven't needed it yet.

has a B&C AVC1 voltage regulator.
