OK, maybe I need to download again.

Shift2: click EP external power and BA bleed air (bleed air switches open and packs should be off for start)

This switch can not be moved:
3. FE console: External power switch: on
The light shows External Power all time, independent from Shift 2 and EP/ BA On or off.

But dual CIVA, TCAS, everything works fine.  :)

@Paul, thanks, I really use dark and cold for all airplanes. Maybe thats the difference. I will try this.
