[s-cars] Proper Solder Technique?

[Fred Munro]

Hi Jim;

Some high-nickel wire types don't take solder well. Corroded wires also will
reject solder, especially if you've only cleaned up the outside of the
twisted wire bundle. You have to fray out the wire, clean up all strands,
and re-twist to get solder to take.
I used to solder all my connections, but I finally broke down and bought a
proper crimping tool. I just replaced the terminal ends on the left front
brake wear sensor by crimping half a butt splice in each wire and insulating
with weatherproof shrink tubing. It worked like a charm - much easier than
soldering and IMO more secure with the proper crimp tool.

on this topic.. I was trying to solder the big-red pad wear sensors to
the factory wiring harness on the urS the otherday..

my question: What makes a wire _not_ want to take solder and how do you
make it?

The ends of the big-red sensors tinned ok, but the wires in the car
didn't want to take the solder. so I just twisted the ends together and
heat-shrinked them.

thanks!

Jim
