Can Jumper Cables Not Work? Inexpensive jumper cables that are not thick enough to carry sufficient current won’t perform to the level you expect, and your car won’t start after a jump. Cables that are too long have more internal resistance, and they may not transfer enough of the donor battery’s power to your car.
Why are jumper cables not sparking? Maybe the battery cables are corroded, the starter is burned out, the car is out of gas, or somebody has stolen your spark plugs to make crack pipes. (In the latter two cases, the “dead” car would crank but not start.) Maybe the battery in the “dead” car is actually fine, but the car won’t start for some other reason.
Can a battery be so dead it won’t jump? YES, a car battery can get so dead it will not receive a jump start anymore. To cut to the chase, and just before we get to the meaty stuff, a “dead” car battery is an indicator of different factors—and almost always, these occur all at the same time.
How long does it take for jumper cables to work? Turn on the engine in the good car and wait two minutes. Then turn on the bad/dead one and wait an additional two minutes. From there you’ll remove the cable in the reverse order at which you put them on, and you’ll let the car run for two more minutes before you get back on the road.
