[V8] Battery discharge issue (update)

[William Gutierrez]

Okay, so I pulled the #7 fuse and decided to check what was disabled by 
pulling the fuse.  Recall that the manual says left side parking lights, 
etc.  Well, they still work!  Only thing I can find so far that doesn't work 
is the aftermarket stereosystem I had installed.  Starting to make a little 
more sense now, but the stereo was installed couple years back so I'm a 
little confused as to why it would be drawing so much power right now.  Can 
anyone suggest how I can test to see if there is a short in the wiring to 
the stereo?

Thanks.
