Hi Paul.

All I see with the APU Test gauge is a black box. Could this be because of these lines in the code:

<!-- BlackBox2 Gauge
     <blackbox>
           <output format="Column" />
           <display units="yes" />
           <gauge file="C:\Users\Paul\Desktop\BlackBox2\Simulation Variables.xml">
                 <variable name="(A:APU GENERATOR ACTIVE,bool)" />
                 <variable name="(A:APU GENERATOR SWITCH,bool)" />
                 <variable name="(A:ELECTRICAL BATTERY BUS VOLTAGE,volts)" />
                 <variable name="(A:ELECTRICAL BATTERY VOLTAGE,volts)" />
           </gauge>
           <gauge file="C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\CS_B737-200\panel\CS737_APU_Gen_Mod.xml">
                 <variable name="(L:E_Batt_bus,bool)" />
                 <variable name="(L:O17_001_SW3,enum)" />
                 <variable name="(L:Apu_strt,bool)" />
                 <variable name="(L:E_APU_on,bool)" />
                 <variable name="(L:O10_005_SW2,enum)" />
                 <variable name="(L:E_AC_TRANS_BUS_1,bool)" />
                 <variable name="(L:E_AC_TRANS_BUS_2,bool)" />
                 <variable name="(L:E_DC_STDBY_BUS,bool)" />
                 <variable name="(L:E_AC_STDBY_BUS,bool)" />
                 <variable name="(L:E_AC_GEN_BUS_1,bool)" />
                 <variable name="(L:E_AC_GEN_BUS_2,bool)" />
                 <variable name="(L:E_AC_MAIN_BUS_1,bool)" />
                 <variable name="(L:E_AC_MAIN_BUS_2,bool)" />
                 <variable name="(L:ApuGenOn,bool)" />
           </gauge>
     </blackbox>

They do not apply to my situation.
1. I don't have the BlackBox 2 gauge installed (although I do have it)
2. My FSX is installed in I:\Flight Simulator X

Should I install the BlackBox2 gauge and change the values to match my setting?
