Title: Boat wiring...
Post by: pyro225 on September 27, 2017, 08:19:07 AM
Hi all - obviously this question is going to come up in my rebuild... and it’s also coming up for my 10yr old regal as it lived in the sea permanently tied to a buoy until I got her 3 yrs back. When I got her all the speaker wiring was green and disintegrating. Ever since half the dials only work with a wiggle of the cables.

Is there a best kind of wire for resisting corrosion? I want to kit the new one out as best I can!

Thanks

Copper will patina in the presence of moisture, just look at the statue of liberty. In wiring, this patina/corrosion is accelerated due to current flow.  Bad thing is it happens especially around crimped ends that can hold moisture.  I build all my own wiring using stranded copper wiring with proper insulation rating for the task.  I use bare crimp on ends, and solder the fitting just at the connector. If you allow solder to travel down the wire, it make a brittle point.  It is possible to strip the wire back and put on new ends, but water generally has a capillary action, and the green runs down the wire some distance.  When a dash board is finished I use an rtv sealant for windshields(no salt)to seal the connections  that are exposed keeping the water out.  Whether the whole harness needs replacement is a difficult decision on larger boats, they get complex.  Some folks are against splicing, but a good soldered and taped Western Union splice will Outlast the life of the boat.  Acceptable on low current items, don't splice main battery cables and such.  Hope this helps.

Thanks - so would you cut them back to see how far the copper runs before taking drastic action?

      If you cut back say 2-3" and the copper is clean or just a little green and the wire remains long enough to reconnect, then I'd use it.   A little patina is ok, just use some fine sandpaper to clean up and crimp new ends on.
