I completely emptied the plugin folder except for Gizmo and rebooted the computer. XPlane would not start so had to reinstall the XPLM plugin. Restarted Xplane but battery switch still down and with no power. Checked plugin folder and still world traffic plugins installed with airports. Removed all the airports with ground traffic plugins, rebooted the computer, and started Xplane. Checked plugins at top of screen which now only shows Gizmo. 737 still started in cold and dark with the batteryswitch cover down and no power to the plane again. Next to the battery switch is a standby power switch. If I lift the cover of that and switch that to battery, all the power comes on, switch to auto and power goes off, close the cover of the standby power switch and all power goes off.
Log file is attached.
