This is a hardware binding issue most often encountered with the Honeycomb system.  The Analog Baron is a complex aircraft that is not responsive to all the hardware binding inputs that are used for very simplistic aircraft.  The following hardware binding events should be used to control the left and right alternators in the Analog Baron:  TOGGLE_MASTER_ALTERNATOR, TOGGLE_MASTER_BATTERY_ALTERNATOR, TOGGLE_ALTERNATOR1, ALTERNATOR_OFF, ALTERNATOR_ON, TOGGLE_ALTERNATOR2.  If your hardware is constantly trying to set either alternator to on or off, especially using the SimVar “A:GENERAL ENG MASTER ALTERNATOR”, the electrical system will not behave correctly.
