When Jumping A Car Which Cable Goes On First?
When a car battery is dead, the easiest way to get it started again is by using another car’s battery. This process is commonly known as jump-starting, and it involves connecting the two batteries using jumper cables. However, it’s important to connect the cables in the correct order to avoid damage to the car’s electrical system or battery.

The first step in jump-starting a car is to park the working vehicle close enough to the dead vehicle so that the jumper cables can reach both batteries. Make sure that both cars are in the park or neutral with the parking brake on, and turn off the ignition on both cars.
The second step is to attach one end of the positive cable (usually red) to the positive terminal of the dead battery. The positive terminal is typically marked with a plus sign (+). It’s important to make sure that the cable clamp is securely attached to the terminal.
The next step is to attach the other end of the positive cable to the positive terminal of the charged battery. Again, make sure that the cable clamp is securely attached to the terminal.
Now, it’s time to connect the negative cable (usually black). Attach one end of the negative cable to the negative terminal of the charged battery. The negative terminal is usually marked with a minus sign (-).
The final step is to attach the other end of the negative cable to an unpainted metal surface on the car with the dead battery. This could be the engine block or another metal surface away from the battery and fuel system. This is done to prevent sparks that could ignite hydrogen gas that may have built up around the battery. The last connection should be made to avoid sparks near the battery.
Once all the cables are securely attached, start the working car and let it run for a few minutes. Then, try starting the dead car. If it doesn’t start, try running the working car for a few more minutes before attempting to start the dead car again. Once the dead car starts, let it run for a few minutes to ensure that the battery has been charged. Then, remove the jumper cables in the reverse order that they were connected, starting with the negative cable on the previously dead car.
Why Is It Important To Know Which Cable Goes On First When Jumping A Car?
Jumpstarting a car can be a risky business if not done correctly. Connecting the negative and positive cables in reverse of their intended order can produce sparking, arcing, or even an electrical fire – making it essential to know which one goes first! Understanding this difference is important for ensuring both your safety and the safety of your vehicle.
Firstly, connecting the jumper cables in the wrong order can result in damage to the car’s electrical system or battery. If the negative cable is connected first, it can create a spark near the battery, which can ignite any hydrogen gas that may have built up around the battery. This can lead to an explosion or fire, causing significant damage to the car and putting the people nearby at risk.
Secondly, connecting the cables in the wrong order can also damage the car’s alternator or other sensitive electronic components. This can result in expensive repairs or even total failure of the car’s electrical system, leaving the car inoperable.
Thirdly, connecting the cables in the correct order can ensure that the car starts quickly and safely. By connecting the positive cable first, you can ensure that the car battery is receiving a charge before starting the engine. This can help prevent further damage to the car’s electrical system and ensure that the battery is properly charged.
Overall, knowing which cable goes on first when jumping a car is essential to ensure a safe and successful jump-start. Following the correct order of cable connections can prevent damage to the car’s electrical system, ensure a quick and safe start, and protect you and those around you from any potential risks.
How Do You Know If Your Car Battery Is Dead?
If your car won’t start, it could be due to a dead battery. Knowing whether or not your car battery is truly dead can help you determine whether or not you need to jump-start the car. Below, we’ll explain how you can know if your car battery is dead.
Engine Cranks Slowly Or Not At All
If the engine cranks slowly or won’t start at all, it could be a sign that your car battery is dead. When the battery is completely dead, the engine may not turn over at all. Or, if the engine does crank, it may sound strained and slow as if it’s struggling to turn over. If you experience this, you can use a multimeter to test the voltage of the battery. If the voltage is lower than 12 volts, then your car battery is most likely dead and will need to be jumped or replaced.
Lights On The Dashboard Dim Or Flicker
If you notice that the dashboard lights or other features on your car are dim or flickering, it could be a sign that your car battery is low. When the battery struggles to maintain enough power to start the engine, it will often result in strange and unpredictable behavior from the car’s electrical system.
If you hear a clicking noise when you attempt to start the engine, it could be a sign that the battery is dead. This noise is caused by the starter motor attempting to turn over but not receiving enough power from the battery to do so. If you hear this sound, it’s likely that your car battery is dead and will need to be jumped or replaced.
Car Won’t Start Or Starts Intermittently
If your car won’t start or starts intermittently, it could be a sign that your car battery is dead. A weak or dying battery will often struggle to provide enough power to the starter motor to turn over the engine. This can result in the engine not starting at all, or intermittent starting and stopping of the engine as the battery struggle to maintain the necessary power.
Corrosion On The Battery Terminals
If you notice corrosion on the battery terminals, it could be a sign of a dead battery. Corrosion is caused by a build-up of sulfuric acid around the terminals, which can prevent the car battery from receiving enough power to start the engine. If corrosion is present, it’s likely that your car battery needs to be jumped or replaced.
Strange Sounds Or Smells
It’s not entirely unheard of for a car to produce strange noises and odd aromas when attempting to start up – both can be indicative signs that the battery is running out of juice. Don’t wait until it’s too late, have your vehicle checked right away by an experienced technician if you encounter anything abnormal while trying to get moving!
If you notice any of these signs, it’s important to have your battery checked by a professional as soon as possible. A battery that is not holding a charge can leave you stranded and can cause damage to your car’s electrical system. Jump-starting the car can temporarily restore power to the battery, but it may need to be replaced to ensure reliable performance in the future.
What Do You Do After Starting a Dead Battery?
Once your car has been successfully jump-started, it’s important to take a few steps to ensure the battery is working properly and will continue to provide reliable power. After jump-starting the car, turn off unnecessary electrical components such as lights, air conditioning, and audio systems and drive anywhere between 10 to 15 minutes to give the battery a chance to charge.
Once you’ve driven for at least 10 minutes, turn off the engine, leave it idle for 5 minutes, and try restarting the car again. If this process is successful, then your battery should be working correctly and you can continue with your journey.
It’s important to note that you should never jump-start your car for more than 5 seconds at a time. If the battery does not hold its charge after 5 seconds have passed, it’s best to stop and allow the car to cool down before attempting again. Additionally, always make sure both cars are in park or neutral and that all passengers have exited the vehicle before attempting to jumpstart it.
How Do You Position the Cars to Jump Your Battery?
Before attempting to jump your car battery, it’s important to ensure that the cables are correctly positioned and connected. When positioning the cars, make sure they are facing each other and at a close distance but not touching. Once in position, identify the negative (-) and positive (+) terminals on both batteries and attach the clamps accordingly.
The red clamp should always be attached to the positive terminal of both batteries and the black clamp should be connected to the negative. Once all clamps are correctly positioned, start up the donor car first before attempting to start your own vehicle.
Jumping a dead battery is a fairly simple job, but it’s important to take safety precautions and adhere strictly to the instructions provided. Following these steps will ensure that you and your car are both safe and that your battery is charged properly before continuing with your journey.
