Since you guys all have your tails apart - I was just curious, on the later 180/185, where is the electrical return located for the tail nav light? (I am referring to the two-wire set-up. The early planes were "single wire" and the electrical return was through the tail cone into the fuselage via the mounting screws.) I believe the later planes had a ground wire and ring terminal attached to the structure somewhere for the return.

You can see where the wire for light is run. The is a 185 in for annual/Tail AD.
one runs forward while the ground is attached to bulkhead. Hope this helps.

That's it. Thanks, I was just curious. Maybe someday I will add a tail strobe and will need a 'real'
ground connection.
