How To Solder Car Electrical Wires

This is similar to the Westinghouse Split connection but you solder the connection for better connectivity and reliability.

How to solder car electrical wires. If youre the belt-and-suspenders sort you can solder after crimping. Soldering temperature is lower for this product than some lead free solders. Tap the end of the 6337 solder on top of the wire splice so the solder melts down into the wires.

Just make sure you use the right size for the wire. Now lay the twisted portion over either side of the joined wires. The trick is you need that wire to wick the solder or its no good.

Run the solder over the entire splice so it can melt and travel into the gaps between the wires. Now i heat it up toward the bottom of the lug until i see the wire underneath pull the solder into it. Join in with this lesson to learn the basics of soldering wires for auto repairs.

How To Solder And Protect Automotive Wiring. Once the connection evenly turns the correct silver color of solder remove the soldering iron and allow the joint to cool. Once cool inspect the union to ensure proper penetration of the solder.

Review the materials needed and learn a few easy soldering methods. Its vital to use a soldering iron that brings the wire up to temperature quickly. You may need to re-tin at some point during the process.

Due to the high level of vibration found in automotive applications a proper solder joint it less ideal than a proper crimp joint For the same reason soldering isnt ideal in an automotive application wire nuts or just twisting the wires together is equally bad. After you are done twisting the two naked wires portion together to the top bend the twisted portion into half. If youre using electrical tape instead apply it once the solder has cooled naturally.
