AUX Battery and DC Meters Selector

[KORDATC 80]

I was just curious as to whether or not when you choose to have one battery instead of two in the FMC options, shouldn't the DC Meters selector change to not have the AUX BAT position. I noticed on the PMDG 737, regardless of what battery option you choose, the meters panel is always in a dual battery arrangement. Best Regards,Robert

Just a guess, but could the AUX BAT position be wired to the the BAT position and display the same values on single battery aircraft?

I don't know I haven't tested it yet, but in the manual it shows single battery aircraft without an AUX BAT position on the DC Meters selector and it shows dual battery aircraft with it.
