So keep reading to find out everything you need to know!

6 Common Causes Behind Jumper Cables Melting

If your jumper cables melted, there’s actually a number of different reasons it may have happened! These reasons include:

The Wrong Gauge

If you are using jumper cables with the wrong gauge, you can cause the cables to overheat and potentially melt. The gauge of a jumper cable is determined by the thickness of its wire. A thicker wire can carry more current and will be less likely to overheat. When using jumper cables, make sure to use the correct gauge for your vehicle.

Touching The Metal Clamps While They’re Connected To The Battery

If you touch the metal clamps together while they’re connected to the battery, you can cause a short circuit. This will cause the jumper cables to overheat and potentially melt. Be sure to keep your hands away from the metal clamps while they’re connected to the battery.

Using Tools To Hold The Clamps

Using a tool like pliers to hold onto both clamps at the same time can cause a great deal of current to flow through the circuit, leading to an overload. This can cause the jumper cables to overheat and potentially melt. Be sure not to short out the circuit by using a

The Condition Of The Jumper Cables

If the jumper cables are frayed or damaged, they may overheat and melt. Be sure to inspect the jumper cables before using them to connect to the battery.

Terminals Connected The Wrong Way

If the terminals are connected the wrong way around, it can cause the jumper cables to overheat and potentially melt. Be sure to connect the jumper cables correctly, with the positive and negative terminals in the correct spots.

Poor Connection From The Jumper Leads To The Either Battery

If the jumper cables are not properly connected, it can cause them to overheat and potentially melt. Be sure to make a good connection between the jumper cables and the battery terminals.

Why Did Your Jumper Cables Catch Fire?

The biggest reason jumper cables may catch fire is due to a poor connection. If the jumper cables are connected the wrong way round, not attached securely, or if the wrong gauge is used, it can create an overload and cause the cables to overheat. This can lead to melting and even fire. Always take the necessary safety precautions when using jumper cables to ensure your vehicle is properly connected and avoid any potential for harm.

Why Did Your Jumper Cables Smoke When Connected?

When the jumper cables are connected to the battery, if there is a poor connection, it can create a spark. This spark can cause the jumper cables to overheat and smoke. So be sure to make a good connection between the jumper cables and the battery terminals to avoid this from happening. Additionally, check the condition of the jumper cables and make sure to use the correct gauge for your vehicle.

How To Tell If Jumper Cables Are Bad?

Exposed/Frayed Wires

If the jumper cables have exposed or frayed wires, they are likely to be damaged and should not be used. Exposed and frayed wires are a sign that the cables may not be able to carry the necessary amount of current, which could lead to an overload and create a fire hazard.

Corrosion

If you see any corrosion on the clamps or terminals of the jumper cables, it indicates that they have been exposed to moisture and should not be used.

Damage To Clamps

If the clamps are damaged, the jumper cables should not be used. Damaged clamps can create a spark and cause the jumper cables to overheat and potentially melt.

Cables Smell Like Burning

If the jumper cables smell like burning, it is likely that they are overloading and could potentially catch fire. Be sure to disconnect the jumper cables from the battery if this is happening and take necessary precautions.

Fraying On The Cladding

If the cladding of the jumper cables is fraying, it indicates that they are too old and should not be used.

What To Do If Your Jumper Cables Smoke/Melt

If your jumper cables smoke or melt, be sure to switch both cars off, disconnect them from the battery and take the necessary precautions. Do not touch the metal clamps while they are connected to the battery, as this can cause an electric shock. Check the condition of the jumper cables and make sure to use the correct gauge for your vehicle. If the jumper cables are frayed or damaged, do not use them.

How To Prevent Jumper Cables Melting

Fortunately, there are plenty of things you can do to stop your jumper cables from melting, smoking, etc. So be sure you’re always doing the following!

Inspect Jumper Cables Before Use

Before anything, you should inspect your jumper cables before you use them to ensure that there’s nothing wrong with them. And, of course, if you do notice a problem, such as fraying or corrosion, then you should avoid using them!

Connect Jumper Cables Correctly

Be sure to connect the jumper cables correctly, with the positive and negative terminals in the correct spots.

Use The Correct Gauge For Your Vehicle

Be sure to use the correct gauge for your vehicle when using jumper cables. Using the incorrect gauge can result in an overload and cause the cables to overheat.

Make A Good Connection Between Jumper Cables And Battery Terminals

To make a good connection between the jumper cables and the battery terminals, be sure to attach them securely. If there is any corrosion on the clamps or terminals, it is a sign that they have been exposed to moisture and should not be used. Additionally, check the condition of the jumper cables and make sure to use the correct gauge for your vehicle. If the jumper cables are frayed or damaged, do not use them.

Store Jumper Cables In A Safe Place When Not In Use

If you are not using the jumper cables, be sure to store them in a safe place. This can mean a few things: keeping them in a dry place, as well as keeping them away from heat and flames. If the jumper cables are stored in a safe place, it can help to prevent any potential for harm.

What To Look For In Good Jumper Cables

A good pair of jumper cables are also going to reduce the chance of melting/smoking occurring. So when you’re purchasing a new pair, make sure you’re keeping an eye on the following!

Heavy Duty Clamps

When looking for good jumper cables, make sure that they have heavy-duty clamps. Clamps like this should be able to securely attach to the battery terminals as well as being corrosion-resistant.

Insulated Cable

It’s important to look for a jumper cable with an insulated cable. An insulated cable will help to prevent any potential electric shocks and keep you safe.

High Current Rating

Check for the current rating of the jumper cables. This will tell you how much current the cables can handle and is an indication of their quality. The higher the current rating, the better quality the cables.

Proper Gauge

Be sure to choose the proper gauge for your vehicle when selecting jumper cables. The wrong gauge can cause an overload and could potentially melt the cables.

Good Flexibility

When handling jumper cables, it’s important to look for those that are flexible. This will make it easier to use the cables in tight spaces and help them last longer.

Length

Be sure to get the proper length of jumper cables for your vehicle. Shorter lengths are better suited for smaller cars, while longer lengths are better for larger vehicles. This will help to ensure that you can make a secure connection between the batteries of both cars.

Price

Lastly, it’s important to look for jumper cables that are priced within your budget. While quality is important, you don’t have to break the bank for good jumper cables.

Having the right jumper cables can make all the difference when it comes to jumpstarting your car.
