What happens if you put jumper cables on in wrong order?
Damaged jumper cables When you reverse the polarity of the jumper cables, you create a drastic increase in the amount of electrical current that runs through them. As a result, the cables may melt or even catch fire.
How do you use jumper cables step by step?
Okay, time for the jump.
- Connect one red clamp to the positive (+) battery post of the “dead” battery.
- Connect the other red clamp to the positive (+) post of the good battery.
- Connect one black-end clamp to the negative (-) post of the good battery.
Do you put positive or negative on first?
“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”
