Fuse Box Help

More digging! I am not ready to claim victory just yet, but I did find something. If this turns out to be true then I have had the problem in my hand several times! Take a look at the picture, see the retaining ring on the interior post lamb bezel, notice it has sprung loose and would touch the lamp socket and grond it to the body! Humm! Directly associated with the circuit in question! I will know for certain after some more time.
