Just solder them together - more Posted by Ari [Email] ![]() ![]() In Reply to: Seat heater wires: just solder them together?............. ->, Bruce, Sun, 29 Jul 2001 20:21:17 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Take the two ends and clean about 1/4 inch of each with some fine sandpaper or Scotchbrite. Slip 3/4 inch or so piece of heat shrink tubing over one wire, and GENTLY twist the wire ends together a little. Just enough to hold them together - the wire is brittle. Then solder the ends. Slip the heat shrink tubing over the joint and heat it with the iron until it shrinks into place.
If you're not familiar with heat shrink tubing, it's a rubbery tubing that, well, shrinks when you heat it. You can pick it up at most electronics places - Radio Shack carries it. It'll shrink down about 3 times its diameter, but the length doesn't change much.
The purpose of the heat shrink tubing is to add a little mechanical support to the joint. The solder is stiffer than the wire, so the solder-wire joint can be a future failure point. With some heat shrink over it, the forces are spread out some. You could also just wrap it with a few turns of electrical tape, but it doesn't work as well - the adhesive on the tape gets gummy when the wire heats up.
Good luck!
