The electrical system of the vehicle may fail or become defective due to moisture, which may contain minerals that are specially damaging to electrical connections and components. Electrical wires may break over time because of their conductors' exposure to salt and sodium chloride, among other things. Usually, when the need arises for connecting electrical wires, one of the best methods is shrink tubing insulation. This effectively connects soldered joints. It is one great technique for keeping the wires safe from moisture and other damaging elements. Here are the steps for connecting electrical wires the safe and easy way:
You'll need these tools:
- Hot air gun
- Soldering iron
- Soldering sponge
- Diagonal pliers/wire cutters
- Wire strippers
- Rosin core solder
- Assorted size shrink tubing
Step 1: See to it that the plugged-in soldering iron will heat up properly. The tip of the iron should be clean, and one way to do this is by wiping it using a wet soldering sponge. The next thing you have to do is to .tin. it. A coat of rosin core solder is what you need. A tinned tip will be in bright silver.
Step 2: Discard about two inches of insulation from the ends of the electrical wires that will be spliced. Make sure that the copper strands won't be damaged when using the wire strippers. Pay extra attention to the gauge-stripping notch. To make installation easier and to prevent damage caused by vibration, electrical systems in the vehicle are usually wired with stranded copper wires.
Step 3: Use shrink tubing that's a bit larger than the outward diameter of the conductor's insulation. You have to cut off a piece with 2-inch length. The tubing should then be slid over the wire.
Step 4: Wrap the electrical wires tightly. This should be done in opposite directions. Prior to wrapping them around each other, the stripped wires must cross each other at a 45-degree angle. Preferably, there should be a one-inch gap from their ends.
Step 5: Be careful in soldering the splice. The tip of the soldering iron should go to the splice's underside so that the splice will heat up. The rosin core solder must be touched to the splice's top. Avoid touching the solder to the iron tip.
Step 6: Place the heat shrink tubing over the soldered splice by sliding it down. This must be on the center. After letting the soldered splice cool down, slide the tubing over the splice. Make sure that the tubing won't shrink because of the solder. Proper positioning is the key here.
Step 7: Blow heat all over the heat shrink tubing with a hot air gun. This will let the tubing shrink down until it's over the soldered splice, intertwined tightly. The right amount of heat will result in an insulated splice that's better protected from the elements.
Note: Use the tools with great care to prevent burns and other accidents. Make sure that the wires are connected properly. Always test the wiring and electrical connection.
