How To Solder Trailer Wiring

Outer diameter of single core wire.

How to solder trailer wiring. Two types of a trailer wiring tester. X2 on the dielectric grease. However when using high-quality materials its not necessary.

It dries fast seals well can be put on in multiple layers and one can goes a long way. Once the connection evenly turns the correct silver color of solder remove the soldering iron and allow the joint to cool. As the heat from soldering propagates down the wire it will crates areas with different levels of brittleness.

I rewire all of my trailers with the plastic 7 way connectors. These differentials in brittleness create areas where vibration can lead to breaks in the wire. Repeat for second light.

Connection three 10-gauge wires together is going to be best accomplished by soldering the connections as this is the most secure method. Use rosin core solder. Solder is often a combination of mixed alloys.

We have a solder gun that comes with solder as well with part PTW2012. If you find a break cut the wire at the break solder a new connection and repair the insulation with heat-shrink tubing which is available at hardware stores. Use a wire jacket or something else around the wires.

I realize that not everyone knows how to solder or wants to learn how so if you wanted to go with the butt connector route youd need to go with 8 gauge butt. The center contains flux that cleans the surface of the wire to be soldered. Simpy solder your wires together for the strongest most reliable connection using a soldering gun.
