    How can I create a update gauge or xml switch that will give the battery
    amps with the engines off. i read a post how fsx has no alternate power source after the master battery is toggled off. But i don't care about the battery being off.
    I want to sit and use ground gpu to keep the batteries alive....:rotfl:\

    please help, on configuring a external gpu.

    Another question. With my lights off, avionics off, engines off and hydraulics off. Where am i getting
    25 amps of draw from?

    heres my elec list:
    Code:
    avionics_bus       = 0, 5 , 15.0
    avionics           = 1, 5 , 18.0
    pitot_heat         = 2, 5 , 20.0
    marker_beacon      = 0, 10 , 8.0
    fuel_pump          = 4, 5 , 17.0
    starter1           = 4, 20, 20.0
    hydraulic_pump     = 4, 20, 20.0
    light_nav          = 0, 2 , 17.0
    light_beacon       = 0, 2 , 17.0
    light_landing      = 0, 12 , 17.0
    light_taxi         = 0, 10 , 17.0
    light_strobe       = 0, 5 , 15.0
    light_panel        = 0, 2 , 8.0
    light_cabin        = 0, 2 , 8.0

    Commands to start Ground Power:

    Code:
    (>K:APU_STARTER) 1 (>K:APU_GENERATOR_SWITCH_SET)
    Commands to stop Ground Power:

    Code:
    0 (>K:APU_GENERATOR_SWITCH_SET) (>K:APU_OFF_SWITCH)

    Thanks Bill, i added the Aux code to the Aircraft.cfg, since this is not a jet.
    But still fails to start. Yesterday i used all 4 apu variables and events and nothing. By the way today i only have 5 amps draw with everything off.

    [Auxiliary Power Unit]
    available = 1

    I added a custom tool tip to watch the battery and the amps....So when the apu starts the battery will stay at 24.0 volts?

    I read this posting you made Bill. I am lost on what it is saying to do, although i do understand it's a few different versions.

    Any ideas?:confused:

    Solved with simple question

    Thank you bill. I replaced my L:var switch with your code and it works, giving me
    91.1 amps. Yesterday i tried using your code in an update and left my L:var using just APU_START.


    SIMPLE QUESTION.........HERE!

    I have another question. This bell's generator is an APU and it runs on fuel? Or is the generator using external power?

    I have been using google books on the bell 205 manual. I will read more in this area tonight...

    Thanks DG,

    The FSX "APU" doesn't actually use any of the a/c's fuel at all. It's as though it's nuclear powered or something... :)

    Note that it will take 5 to 10 seconds after sending the (>K:APU_STARTER) before electrical power will appear.

    I added an APU light detecting volts.
    But it starts after 1 second and works well.

    I figured the APU will be for an Aux Power unit when parked and the generator runs from the fuel or the APU. Not sure! i plan to make a sound for the generator. APU does not need one.

    Update

    Here is what I learned recently.

    The Bell 205 has a main generator and a standby gen. Also if the main fails the starter generator can be used as a main gen. They also suggest using a GPU for start up. So I decided to make the APU system work for the standby gen and the GPU. This allows the main generator to use failures in the game. Just switch over to the standby generator.

    Any tips would be great!
