[C320-list] Bow running light wiring problem

[Scott Thompson]

Maybe this helps: I had the wood panels above and below the shelf at the 
front of the vberth on my 1999 boat removed recently for windlass 
maintenance and for purposes of installing hose for washdown pump in the 
anchor locker. I also cut out the non-structural fiberglass panel behind 
the upper wood panel to give me better access. After doing so I noticed 
a wire running high along the port side of the hull towards the pulpit. 
I suspect that the wire runs through the port side wiring channel behind 
the trim in the vberth.
