Where does the negative go when jump starting a car?
The negative will go to a ground and the positive will go to the starter and to the alternator. If those are correct, ensure that the jumper cables are correctly aligned. Some sets I’ve seen will have black shielding on both with a thin yellow (or some other color) stripe up them.
What happens when jumper cables are reversed on a battery?
Damage to the Batteries. Connecting the positive terminal of each battery to the negative terminal of the other battery will result in a huge surge of electrical current between the two batteries.
What’s the difference between positive and negative jumper cables?
The positive jumper cable should attach both batteries’ positive poles while the negative jumper cable attaches the two negative battery poles.
Is it possible to get a positive spark when jumping a car?
minor note: It’s not 100% guaranteed that negative goes to ground/car body. A minority of positive ground cars exist, probably older/vintage.. In any case you never see “significant” sparking when jumping cars. It’s nigh on certain the wires are crossed up/ connected “positive-to-negative” if sparking is significant.
The positive jumper cable should attach both batteries’ positive poles while the negative jumper cable attaches the two negative battery poles.

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.
How do you jump start a stalled battery?
Connect one end of the red (positive) jumper cable to the positive terminal on the stalled battery. 3. Connect the other red (positive) cable to the positive terminal of the good battery. 4. Connect one end of the black (negative) jumper cable to the negative terminal of the good battery.
