A dead battery can be a bummer. It can also be a dangerous job jump starting it. Some do it differently. This is how I do it.
Difficulty Level: average Time Required: 15 minutes
Here's How:
- Make sure both batteries are the same voltage.
Bring the running vehicle up to the front of the dead vehicle. They must not tough. - Make sure all emergency brakes are applied and all vehicles are in either park or neutral.
- Cover the cell caps with a rag. Do not cover the terminals.
- Put on some safety glasses.
- Get your jumper cables. Make sure they are good ones with no frays anywhere.
- Connect one red handle clamp of one end of the jumper cables to the positive side of the dead battery.
- Connect the black handle clamp of the same end of the jumper cables to a good ground besides the negative side of the good battery. An alternator bracket usually works well.
- Take the red handle clamp on the other end of the jumper cables and connect it to the positive side of the good battery.
- Connect the remaining black handle clamp to the negative side of the good battery.
- Start engine of starting vehicle.
- Start dead vehicle.
- If it does start right away rev up the running vehicle a little and just let it run for about ten minutes charging up the dead battery a little. Then try again.
- If this doesn't work charge the dead battery with a battery charger. You should do this slowly over night.
- If this doesn't work the dead battery probably needs to be replaced.
- Be careful not to cause a spark. This could make a battery blow up.
