Hi, I have been happily flying the C172 for the last couple of weeks, but starting yesterday, I started having problems with power.

I follow normal start procedure and end up with motor running and active G1000. Then, however, sometimes the power suddenly goes away, and the G1000 goes dark. Flaps will no longer move etc.

 

Last time it happened while taxiing, the time before it happened while climbing.

This last time I toggled the battery and power returned, then it disappeared again a few minutes later, and this time I could no longer bring it back.

As far as I can see I have not enabled any failures-

Am I doing anything wrong here?

 

Maybe you forget to start the Alternator?

Are you using a Honeycomb Alpha yoke?

The most common cause of issues like this, are duplicate or problematic assignments that conflict.  Eg. If you use the mouse to start the aircraft (not the Honeycomb's controls) and then start to use the Honeycomb, it will suddenly pick up that the avionics master (or battery) is turned off, and turn it off in the sim.

Even if you don't use the Honeycomb, you may have a duplicate assignment that is turning off either the alternator or avionics switch, inadvertantly.
