Can battery cable go bad?
Another symptom of a bad or failing cable is the presence of corrosion on the terminals. Corrosion develops as a result of the acidic vapor produced by the battery when it becomes hot from exposure to the heat of engine operation. Over time, the vapor can begin to corrode the terminal and cause corrosion to build up.
Can a loose battery cable cause a fire?
A loose battery may shift due to vibration or road bumps causing terminals to contact conductive surfaces. If the contact is maintained, heating and fire may result. Collision damage may cause displacement of the battery, shorting of cables or damage to the battery case that can result in fire.
What happens if negative battery cable is loose?
A loose battery terminal affects the flow of electricity. There is less power going to the electrical systems and the vehicle will not start or start sluggishly.

“Electricity is flowing through the cord and by stepping on it you are impeding the flow of electricity and creating heat restrictions. This causes the wiring that is inside the receptacle the cord is plugged into to fray and become burned.”
How do loose wires cause fires?
Loose electrical connections result in high resistance, making it more difficult for current to flow. The end result is heat, damaged insulation, burned insulation, melted wires, melted terminals, melted terminal strips, fire and even explosions.
Which battery cable is positive/negative?
Car battery cables are usually colored to match their use: red cables are positive, black cables are negative. In some cases, the wires may both be black, but they will have red and black boxes or accents at the ends of the cable.
