Season's greetings everyone!

I'm experimenting with creating my own modules and ran into a big unknown.  
The rack frame and power supply should supply +5 volts and +/- 12 volts.  
However, it *seemed* (and I probably did something wrong) that the +5 volts 
was not there.  To check, I built a simple circuit with a resister, and used 
a volt meter to check the presence of the +5 volts.  Nada.  This seems 
strange, because all my modules are working just fine.

The LED next to +5 volts isn't on.  The LEDs near +/- 12 volts is on.  
Perhaps those LEDs turn on only when a module uses that power source?

Does anyone have experience in tapping into this +5 volt source?  Can 
someone instruct me how to build a simple circuit that uses this power 
source?

Much thanks!  I'm obviously more ambitious than experienced...
