Voltage reading on tank display

Is the voltage reading on the tank display supposed to be chassis batteries or house batteries.  As I am writing this the inverter/charger display shows 13.4 volts on house batteries and the tank monitor shows 12.3 volts.  This is on a 2005 U320

Steve,

Might want to verify:  check voltage at each battery bank.  Hopefully 12.3 is not an actual reading on either battery bank, as that is very close to 50% discharged.

I wonder where that sense input is connected. Definitely my engine batteries as it started too well.
