Why did my jumper cables start smoking?
If there is too high amperage being transferred with the cables, that can melt the insulation and cause smoke. If they are transferring that much power, disconnect them and let them cool, since you’re pulling that amount of DC current off the running car and it’s battery, which is also a bad thing.
When jump-starting a car which cable goes last?
Connect one end of the red (positive) jumper cable to the positive terminal on the stalled battery.
- Connect the other red (positive) cable to the positive terminal of the good battery.
- Connect one end of the black (negative) jumper cable to the negative terminal of the good battery.
What happens if you connect the jumper cable backwards?
Car owners may accidentally connect the jumper cables in reverse order or install the battery backward, which causes the vehicle to no longer start. The purpose of this troubleshooting guide is to help answer the following questions: Hooked battery up backward now car won’t start.
What should I do if my car JumpStart does not match?
If they do not match, serious damage can occur to both vehicles. Park the cars close enough for the cables to reach, but they should not touch. Turn the engine off in the car with the good battery. Unplug any accessories (like cell phone chargers); the power surge generated by the jumpstart can short them out.
What causes a jumper cable to spark on a battery?
These items will attempt to draw power from the battery. This means the electrical system is drawing current, and the battery is part of that system. Sometimes this can cause the battery jumper cable to spark when it’s connected to the battery post.
What should I do if my car jumps over a cable?
Verify the voltage of the battery in the vehicle doing the jumping. If they do not match, serious damage can occur to both vehicles. Park the cars close enough for the cables to reach, but they should not touch. Turn the engine off in the car with the good battery.

What does the negative terminal sign on a car mean?
The negative terminal will have a (-) sign and black wires or a black cover. The terminal covers may have to be moved to reach the actual terminal. If the terminals are dirty or have corrosion, use the wire brush to clean them off.
