1. Understanding Why Your Car Won't Start
Before jumping into the process of how to jumpstart a car, it's essential to understand why a car might fail to start. A common reason for this is a dead battery. Batteries can die for a variety of reasons, including:
- Leaving the lights on for too long.
- Worn-out battery that can no longer hold a charge.
- Cold weather, which can reduce a battery's effectiveness.
- Faulty alternator, which fails to charge the battery properly.
If you suspect your battery is the issue, jumpstarting the car is usually a quick fix to get you back on the road. However, if the battery is old or completely dead, you might need a replacement soon.

2. What You’ll Need to Jumpstart a Car
To jumpstart your car, you will need a few tools and some basic knowledge. Here’s what you’ll need:
- Jumper Cables: These are essential for connecting your dead battery to a charged one. Make sure they are long enough to reach another car's battery and are in good condition.
- Another Vehicle with a Working Battery: This is needed to transfer power to your car. Ideally, the other car should have a battery of the same voltage (12 volts for most cars).
- Gloves and Safety Glasses: Protect yourself from any accidental sparks or battery acid.
Once you have all your tools, you’re ready to start the jumpstarting process. Now, let’s get into the step-by-step guide!
3. Step-by-Step Guide to Jumpstarting Your Car in a Parking Lot
Follow these steps carefully to safely jumpstart your car in a parking lot. While the process is relatively straightforward, it’s important to perform each step correctly to avoid damage to your vehicle or injury to yourself.
3.1 Position the Cars Correctly
The first step is to position both vehicles. Park the working car close enough to your car that the jumper cables can reach both batteries, but make sure the cars are not touching. Both vehicles should be in "park" or "neutral," and the parking brake should be engaged on both cars for safety.
3.2 Turn Off Both Cars
Before connecting the cables, make sure both cars are turned off. It’s important to prevent any electrical surges that could damage your car’s electrical systems.
3.3 Connect the Jumper Cables
Now comes the crucial part: connecting the jumper cables in the correct order. Follow these steps:
- Red to Dead: Start by connecting one end of the red (positive) cable to the positive terminal of the dead battery in your car. This is usually marked with a "+" symbol.
- Red to Donor: Connect the other end of the red cable to the positive terminal of the working battery in the other car.
- Black to Donor: Next, connect the black (negative) cable to the negative terminal of the working car’s battery. This terminal is usually marked with a "-" symbol.
- Black to Ground: Finally, connect the other end of the black cable to an unpainted metal part of the engine block or the car frame of your car, away from the battery. This helps prevent any sparks near the battery.
3.4 Start the Donor Car
With the cables securely connected, start the engine of the working car. Let it run for a few minutes to allow the battery to transfer power to the dead battery.
3.5 Start Your Car
After a few minutes, try starting your car. If the battery has enough charge, it should start right up. If it doesn’t start immediately, wait a few more minutes before trying again.
3.6 Disconnect the Cables in Reverse Order
Once your car is running, it’s time to disconnect the jumper cables. Always remove them in the reverse order that you connected them to avoid any short circuits:
- Remove the black (negative) cable from your car first.
- Then, remove the black (negative) cable from the donor car.
- Remove the red (positive) cable from the donor car.
- Finally, remove the red (positive) cable from your car.
Once the cables are removed, leave your car running for at least 20-30 minutes to allow the alternator to charge the battery further. If the car stalls again shortly after turning it off, you may need to replace the battery.
4. What to Do If Jumpstarting Doesn’t Work
If your car still won’t start after jumpstarting, there could be a deeper issue at play, such as a faulty alternator, starter motor, or fuel delivery problem. It’s best to call for roadside assistance or a tow service at this point. I’ve found that many roadside assistance services offer emergency towing, so you can get your car to a mechanic for a proper diagnosis and repair.
4.1 Towing Services Available Near You
In case the jumpstart doesn’t work, it’s important to know that towing services are available to help you. Many local towing companies provide emergency services, including roadside assistance for car issues like dead batteries. In urban areas like Portland, OR, towing companies are equipped to handle such emergencies, ensuring quick response times and reliable service.
4.2 Battery Replacement Services
If your battery is old or damaged, some towing companies offer battery replacement services on-site. They can bring a new battery to your location and get you back on the road in no time. It’s a convenient service, especially when you don’t want to deal with the hassle of getting your car to a shop.
5. Conclusion: Stay Prepared and Stay Safe
Jumpstarting a car in a parking lot can be a quick and effective way to get your car running again, especially if you’re in a pinch. With the right tools, some basic knowledge, and a little patience, you can solve the issue and continue your day without major interruptions. But remember, if the jumpstart doesn’t work or you’re unsure about the process, don’t hesitate to reach out to a professional for help.
