I just couldn't figure out why the cabin light in my P-19 stopped =
working. =20
I checked the bulb...good; the light fixture...good; the fuse... also =
good. All that was left was the wire, and those of you that have looked =
at that mess of unmarked wires in the Starboard cabinet know what a =
problem I was facing.
I decided the quickest way to solve the problem was to expose as much of =
the wire as possible. I couldn't get to the piece that runs across the =
cabin top to the mast stanchion, but I was able to follow it back from =
the bottom of the stanchion to the fuse block. With the exception of =
the area, by the bottom of the stanchion, where the wire exits the =
snap-on wire duct everything looked OK. =20
As the bottom of the steel wire duct was a rusty mess I pulled it off. =
Upon inspecting the tight bend in the wire caused by the duct I found a =
small crack in it's casing. I stripped the casing back and found a =
small crack in the covering on the red wire. Striping the red wire =
revealed a green mass of copper corrosion about an inch long where the =
wire should have been!
I took the "U" channel duct into the shop and cut off about 4" off of =
the bottom. Starting at the "new" bottom end, I sanded off the paint =
until I didn't find any more pockets of rust, about 12". A couple of =
coats of instant galvanizing and it is ready to top coat. =20
I'm not going to mess with a splice in the wire (as it is in a location =
that would make it prone to have problems) but plan to replace all ten =
feet of it from the top of the mast stanchion to the fuse block. When I =
reinstall the duct, I am going to leave the gap at the bottom and just =
tape the wire to the stanchion with white tape (will match the paint on =
the bottom of the stanchion).=20
Side note: While down there, I noticed that under the white paint on =
the bottom of the stanchion, the wood is starting to turn black! Next =
project will be to try to figure out how to remove it from the boat so =
it can be soaked it in "Get-Rot".
