How To Solder Automotive Electrical Wires

Clean the area to be soldered scraping the wire down to bare metal and then wiping it clean with alcohol or acetone.

How to solder automotive electrical wires. The best solution to cover soldered wires is heat shrink tubing and it must be installed BEFORE the soldering is done. Repeat this process on the other wire. This helps to spread out the heat when the tip touches the wires.

When melting the solder to the wires try not to touch the iron with the solder. Try sourcing some alli solder it may work for your particular wire. You also have to route and support your wires in such a way that they dont flop around.

Twist the ends together on the other splice area. Automotive applications use 6040 containing 60 tin and 40 lead. In this video Ill show you three different ways of soldering Automotive WiringNote.

The most secure and durable way to splice two wires together is to solder them. Remove the soldering iron and wait a few seconds to let the soldered connection cool and harden. Bend the ends of both tinned wires into a U-shape with needle nose pliers.

This process should melt the solder and coat both wires evenly. These I then insert into GM Weatherpack fittings with a bit of dielectric grease on the pins. Instead allow the iron to heat the wire to the point that it melts the solder.

The most reliable way of joining two wires together is by soldering. Just make sure you use the right size for the wire. When stripping leave the insulation being stripped from the wire covering the tip of the wire so that it can be easily removed by hand but so that it protects wire strands from fraying at the endpoint.
