George, I don't know. Until I read Darryl's message, I didn't know
that wire was sometimes tin plated. To me, the word "tinned" meant
that it had solder applied to it.

One thing he points out is not to tin a wire you'll use a crimp
connector on, nor should you solder a crimped connector. You shouldn't
do the second because it destroys the strain relief, and you shouldn't
do the first because the connection loosens over time. Very, very
interesting, because Tefzel wire is pre-tinned...

Pretinned and "bunch tinned" as we used to call it are different; the
pretinned has each strand tinned. Bunch tinned has the group of
strands "glued" together with tinning or solder. Which is Tefzel
aircraft wire?

Aside ... back in the 1970's, the best wiring for boats was considered
to be the bunch tinned; a combination of good vibration resistance and
corrosion protection according to the wire salesmen calling on us
trying to get our chief engineer to use it on mobile radios. It was
said to be formable to a path but resistant to fatigue failure.

I AM NOT STATING THAT AS FACT, rather as what we were told.
