Your not really checking for a short.  A short is when your positive circuit 
is connected directly to ground.  This condition would typically not last 
very long as the wire would get hot and usually melt or be glowing.

You want to look at what that fuse that you pulled out is connected to.  
Check your Bentley.

 that normal when a car is not running with no key in the ignition and the

I'm confused by what you mean by "power passing through".  There are a few 
fuses that always have 12 volts on them.  If you touch a test light to either 
end of the installed fuse and the other to ground, you will get your light to 
turn on.  The trick is to remove the fuse and put your test light accross the 
terminals that were holding the fuse.  If you get a light, then you have a 
device that is using power.  Again, look at a (Bentley) schematic to see what 
devices are connect to that particular fuse and try disconnecting each 
device, one at a time.  (don't confuse current flow vs. voltage.  you can 
have 12 volts on a wire but not be consuming any power)
HTH.
