Troubleshooting a Dead Battery
Before assuming your battery is dead, check for simple issues like loose battery connections or a blown fuse. If these are not the problem, jump-starting is the next step. Ensure you connect the jumper cables correctly to avoid damage. If the car starts, let it run for a while to recharge the battery. If the battery repeatedly discharges, professional diagnosis is necessary.
Jump-Starting Your Car
- Connect the positive (red) cable to the positive terminal of the dead battery.
- Connect the other end of the positive (red) cable to the positive terminal of the working battery.
- Connect the negative (black) cable to the negative terminal of the working battery.
- Connect the other end of the negative (black) cable to a metal ground point on the car with the dead battery, away from the battery itself.
- Start the working car and let it run for a few minutes.
- Try starting the car with the dead battery.
- If it starts, disconnect the cables in the reverse order.
