DC BAT indicator — hot or switched bus?

[andreasxb]

I remember I read somewhere, likely manuals for the 737-200, that you should turn the DC voltage indicator to a position other than BAT as part of the shutdown procedure to prevent battery drain through the indicator.

Wait, I found it: http://www.b737.org.uk/electrics.htm

So it says that BAT is connected to the hot battery bus and therefore would indicate even when the BAT switch is off. In the IXEG 733 it does not do that. So, is that a bug or a real world option or change?

I habe never heard of that, so I assume its only valid for some (older) configurations.

In our model the BAT position shows voltage of the battery bus.
