I can see no signs of corrosion even after stripping large lengths. Had the 30 year old windspeed meter on my sailboat cease working recently. Investigation revealed the 60 foot sensor wire had a break in it somewhere. Connections looked OK. No visual sign of damage, but cutting it in about the middle revealed black crumbs instead of copper wire. Turns out entire lengths of the wire had corroded to dust. Probably had worked so long because it was only handling a half volt or so AC signal. It was non-tinned and had lousy insulation, sort of like extension cord wire. So it can happen, at least in small gage wire. |
