If you have black holes where some of the gauges should be, you have
probably copied the necessary gauge files to the wrong folder. This is
usually due to an additional directory which was added to preserve the
integrity of your default gauges. First make sure you have unzipped your
L188Electra file to the correct directory, This will usually be C:\Program
Files\Microsoft Games\FS2002\Aircraft.
After unzipping, open the L188Electra folder and then open the "gauges"
folder. Copy the entire contents of this
folder to your MSFS2002Pro Gauges Folder. It can usually be found at:
C:\Program Files\Microsoft Games\FS2002\Gauges
***NOTE*** When you open the C:\Program
Files\Microsoft Games\FS2002\Aircraft\L188Electra\Gauges folder, you will
see several CAB files along with another gauges folder. COPY ALL OF THE CAB
FILES AND THE COMPLETE GAUGES FOLDER, INTACT TO THE FS 2002\gauges folder.
Otherwise you will have a good number of black holes in your panel.
