How to jumpstart a car with jumper cables or How do you use jumper cables to jumpstart a car
A. Prep Phase
Position both vehicles close enough so cables can reach both batteries. Park, turn off ignitions, and apply parking brakes (always a safety first step).
Open hoods and locate the battery terminals, noticing the red (positive) and black (negative) posts
B. Hooking Up Jumper Cables
Connect the red clamp to the positive terminal of the dead battery.
Connect the other red clamp to the positive terminal of the working battery.
Connect the black clamp to the negative terminal of the donor battery.
Attach the final black clamp to a metal grounding point on the disabled vehicle away from the battery.
