I have imperfect continuity of +ve wire only between wago harness connector block1.10 and spade connector of +ve of Aqua Signal forward nav. light incandescent bulb. I can't follow the cable further aft than stbd locker of fwd cabin, where it runs in a tray formed by the upturned edge of the overhead ceiling molding. Can anyone say exactly where this cable runs between fwd cabin and the connectors behind the distribution panel on port side above nav table? Does it run in a conduit (that I might pull a new/replacement cable through)? Where does it cross over from stbd to port side? And has anyone had to deal with this before? For info, the cable (pos and neg) is in a grey vinyl sheath near the light, and the +ve wire that leaves the wago blocks has brown insulation.
