KingAir internal lights only with EXT PWR?

Guenseli

I wonder what I do wrong or if its a bug or if its by design:

I can turn the internal lights (flood, integrated, instrument, etc) only activate when I connect external power.

Why not on battery?

thx

We've added the manual and a FAQ doc to the support page for the King Air

For starts at night on battery power, ensure that the BUS TIE switch is in the MAN CLOSE position. The King Air uses a five-bus system with the left, right, and center buses, sometimes connected through two bus-ties. When external power is applied, one generator is online, or the BUS TIE switch is placed in the MAN CLOSE position, both the left and right bus ties are activated, sharing voltage across all three buses. See the electrical schematics section for more details.
