How to Properly Jump Start a Car

Introduction

Jump starting a car is a crucial skill for any driver. Whether you've left your lights on or your battery has simply aged, knowing how to safely jump start a car can save you from getting stranded. This guide will walk you through the proper steps to jump start your vehicle effectively and safely.

Step 1: Prepare for Jump Starting

• Find a Working Vehicle: Locate a car with a functioning battery and park it close enough so the jumper cables can reach both batteries.
• Safety Precautions: Ensure the two vehicles do not touch. Remove the keys from the ignition of both cars to avoid accidental starting.
• Identify Battery Terminals:
  • Locate the batteries in both vehicles.
  • Identify the positive (red) and negative (black) terminals.

Step 2: Set Up the Jumper Cables

• Unravel the Jumper Cables: Spread out the cables to avoid tangling. Each hand should hold one red and one black cable.
• Connect to the Dead Battery:
  • Attach the red cable to the positive terminal of the dead battery.
  • Ensure a secure connection by wiggling the clamp if necessary.
• Select a Ground for the Negative Cable:
  • Instead of connecting to the negative terminal of the dead battery (to avoid sparks), find a good grounding point on the vehicle's frame or engine block.

Step 3: Connect to the Good Battery

• Attach Cables to the Good Battery:
  • Connect the red cable to the positive terminal of the good battery.
  • Connect the black cable to the negative terminal of the good battery.
• Check for Clearance: Make sure the cables are not near any moving parts, like cooling fans or serpentine belts.

Step 4: Jump Start the Car

• Start the Donor Vehicle: Start the engine of the vehicle with the good battery and let it run for about two minutes.
• Attempt to Start the Dead Vehicle: Try starting the vehicle with the dead battery. If it doesn’t start immediately, wait a few more minutes and try again.

Step 5: Disconnect the Cables

• Remove Cables in Reverse Order:
  • First, disconnect the negative terminal from the dead battery.
  • Next, remove the positive terminal from the dead battery.
  • Disconnect the negative terminal from the good battery.
  • Finally, remove the positive terminal from the good battery.
• Avoid Sparks: Ensure that the cable ends do not touch each other or any metal surfaces during this process.

Step 6: Troubleshooting

• If the Car Doesn't Start:
  • Let the donor vehicle charge the dead battery for an additional five minutes and try starting again.
  • If still unsuccessful, check all connections to ensure they are secure.
  • If only a clicking sound occurs, the battery might be permanently damaged.

Step 7: Using a Portable Jump Starter

• Connect the Portable Jumper:
  • Ensure the device is turned off.
  • Connect the red cable to the positive terminal and the black cable to the negative terminal of the dead battery.
• Turn on the Device: Switch the jumper to the on position and start the car.
• Disconnect After Starting: Once the car starts, turn off the portable jumper and disconnect the cables.
