[C320-list] Knot Meter Sender Replacement

[crashley at gte.net]

I had the same problem running new cables for my Raymarine wind instrument 
and auto pilot (too many wires in the Edsen tubes). Don't be afraid to cut 
the cables and resplice. Just to be sure the connection is good, you may 
want to solder the wires back together. I did this for my autopilot fluxgate 
compass, but even a crimp splice will probably be good for years.
