I've written an XML gauge to remedy the battery dying while the APU or Ground Power is activated.

This is just the APU fix. I'll try and combine the Gound Power at a later time

First, thank you for this fix, fsxPaul. Second is there a temp fix for the ground power now?

Hi Paul.

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

[i]<!-- BlackBox2 Gauge
     <blackbox>
           <output format="Column" />
           <display units="yes" />
           [b]<gauge file="C:\Users\Paul\Desktop\BlackBox2\Simulation Variables.xml">[/b]
                 <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>
           [b]<gauge file="C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\CS_B737-200\panel\CS737_APU_Gen_Mod.xml">[/b]
                 <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>[/i]

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 [b]I:\Flight Simulator X[/b]

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

Please be patient. I've just finished the Gound Power fix and will be posting to the Avsim library shortly.
Stay tuned

THX a lot !!!
