Perform a Jumpstart
When dealing with a dead car battery, performing a jumpstart can get your vehicle back on the road. Here’s how:
- Step 1: Position the running vehicle next to yours, ensuring they are close enough for the jumper cables to reach but not touching.
- Step 2: Turn off both vehicles and locate their batteries and terminals.
- Step 3: Connect the red (positive) jumper cable to the positive terminal on the dead battery, then the other end to the positive terminal on the working battery.
- Step 4: Connect one end of the black (negative) jumper cable to the negative terminal on the working battery, and the other end to an unpainted metal surface under the hood of the car with the dead battery.
- Step 5: Start the vehicle with the working battery and let it run for a few minutes to charge the dead battery.
- Step 6: Try to start your car. If it doesn’t start, recheck the cable connections and let the battery charge for a few more minutes before attempting again.
Remember, safety comes first when jumpstarting a car battery. If you’re unsure of the process, it’s best to seek assistance from a professional.
Test the Alternator
When dealing with a dead car battery, testing the alternator is crucial to prevent future breakdowns. Here’s how to check this vital component:
- Start the Engine: Once you’ve jump-started the car, let it run for a few minutes.
- Use a Multimeter: Set the multimeter to DC voltage and connect the red lead to the positive battery terminal and the black lead to the negative terminal to measure the voltage.
- Check the Reading: A healthy alternator should show a voltage reading between 13.5 to 14.5 volts.
- Rev the Engine: Increase the RPMs to around 2000 and recheck the voltage. If it remains stable or increases slightly, your alternator is likely in good condition.

- Prepare the Charger: Connect the charger to an outlet and set it to the correct voltage and amperage.
- Connect the Charger: Connect the charger to the battery, ensuring proper polarity (+ to +, – to -).
- Charge the Battery: Turn on the charger and let it charge the battery fully.
- Disconnect the Charger: Once fully charged, disconnect the charger ensuring a safe removal.
Remember to regularly check your battery’s health and charge it when needed to avoid any unexpected breakdowns.
