When I select the default Baron or C172 to start the flight with engines off (because I like to do the stating sequence from cold and dark), I just cannot turn on the GPS and radios. I select master battery ON, avionics master ON, I click buttons on GPS and radios stack and still get black gauges. The only way I can get things working again is to reload the aircraft with the "start with engines running" option checked.
I just don't know what is happening, please help.
