There is a large amount of electrical current trying to travel from one battery to the other. So whenever a connection isn’t snug and made complete, that electricity causes the cables to become exceedingly hot, thus melting the line.

Why are my jumper cables melting and smoking?
The single most common reason for melted jumper cables is a misaligned connection. When connecting jumper cables from one car battery to the other, you must make sure that the cable's clamps are connected to the corresponding terminals on the battery.
Why did my jumper cables smoke and melt?
There is a large amount of electrical current trying to travel from one battery to the other. So whenever a connection isn't snug and made complete, that electricity causes the cables to become exceedingly hot, thus melting the line.
What causes jumper cables to spark?
That's why it is recommended that you connect the negative jumper cable to the vehicle body and not the negative post of the battery. This is so you can avoid sparks from occurring near the battery where flammable hydrogen gas may be present, resulting in a possible explosion.
Connecting Jumper Cables Backwards? Here'S What Could Go Wrong!
What causes positive battery cable to corrode?
When you see corrosion on the positive terminal, this means the battery may be overcharging. The substance can be either greenish blue or white depending on the type of metal of the terminal ends. If the substance is greenish blue, its copper sulfate.
How do you know when jumper cables are bad?
- Any visibly exposed metal wire. - Fraying of the wires near the clamps. - Corrosion or rust on the clamps themselves.
Why would battery cables start smoking?
There is a faulty, high resistance (often due to corrosion, wire defect or break or loose mechanical connection) connection at the battery post and/or at the vehicle ground(s) at the frame.

What causes jumper cables to not work?
Jumper cables that are too long, or not heavy enough, have excessive internal resistance or cannot carry sufficient current may not work when you need them. So invest in a set of quality jumper cables.
What does it mean if my jumper cables are smoking?
Human error is the most common cause of jumper cables smoking, heating up, or melting while trying to jump-start a vehicle. Anyone attempting to jump-start a vehicle first needs to learn how to do it correctly and safely. That will eliminate most causes of smoke, heat, or melting jumper cables.

How do you prevent positive terminal corrosion?
Apply battery-terminal grease to the terminals to help prevent corrosion. It's available at any auto parts store and usually comes in a little ketchup-like packet. Another great option is AMSOIL Heavy-Duty Metal Protector. It creates a protective coating on terminals that wards off corrosion.
What causes battery cables to melt?
High resistance and high current flow will cause battery terminals to melt. When electrons are restricted to pass through, it will create heat. Depending on the amount of resistance buildup near battery, that much heat will be generated. Resistance can be too high to the point that terminals can melt.
