How do you perform a solder repair on a broken wire in a wire harness?
Twist the broken wire around the new wire and wrap it toward the new wire insulation. Twist the ends together on the other splice area. Place the soldering iron on the exposed pieces of copper for three to five seconds. Touch the solder close to the solder iron tip.
What is the best solder for automotive wiring?
“Be sure to use automotive-grade stranded wire.” You’ll want a 60-40 rosin-core solder, Popular Mechanics explained. This means it is 60 percent tin and 40 percent lead. The rosin core contains a flux, which will melt before the metal begins to.
What’s the best way to solder a wire?
Soldering uses a hot iron to heat the wires to a temperature that will melt the solder, which when it cools takes care of the sturdy physical connection and the electrical conductivity. However, soldering is also a great source of distress amongst novices.
Can a wiring harness be repaired with soldered joints?
I have repaired many wiring harnesses with soldered joints (made the joints very slim so that the repair looked as per original once taped up – no bulges etc) both in the engine bay and under the dash. Soldered joints do not have any problems and, done properly, will have a lifetime longer than the vehicle.
What kind of solder to use on a motorcycle?
You want some wire solder in a gauge that is narrow enough to melt easily with the wire gauge most commonly found on motorcycles, usually 18 gauge for most purposes. I usually buy solder without the rosin core, preferring to use a dab of flux on the bare wires before heating them and applying the solder.
Can a soldered connection break due to vibration?
A properly soldered connection should not break due to vibration. NASA uses soldered splices in their wiring harnasses. See: https://workmanship.nasa.gov/lib/insp/2%20books/links/sections/407%20Splices.html
