Leaving the engines running during a jump-start can be dangerous. It increases the risk of electrical sparks and potential explosions, especially if the jumper cables are connected incorrectly.
- Prevent Electrical Damage:
With the engines running, there's a greater chance of damaging the electrical systems of both vehicles. The sudden surge of power from the working car's battery can overwhelm the electrical components of the dead car.
- Protect the Jump Starter Vehicle:
Leaving the engine running in the jump starter vehicle puts added strain on its battery and charging system. This can lead to premature wear and tear, potentially shortening the lifespan of the battery.
- Reduce the Risk of Accidents:
Having the engines running during a jump-start can be distracting and increase the risk of accidents. It's best to eliminate any potential distractions and focus solely on the task at hand.
Therefore, always remember to turn off the engines of both vehicles before connecting the jumper cables. This simple step significantly reduces the risks associated with jump-starting and helps ensure a safe and successful procedure.
Engage parking brakes.
Engaging the parking brakes on both vehicles involved in a jump-start is a crucial safety precaution that serves several important purposes:
- Prevent Rolling:
Engaging the parking brakes helps prevent both vehicles from rolling during the jump-start process. This is especially important if the vehicles are parked on an incline or uneven ground.
- Reduce Strain on Transmission:
With the parking brakes engaged, the transmission is locked, reducing the strain on the transmission components. This is particularly important in automatic transmission vehicles, as leaving the transmission in "Park" without engaging the parking brake can put stress on the parking pawl.
- Added Safety:
Engaging the parking brakes provides an extra layer of safety in case the jump-start procedure doesn't go as planned. If there's a sudden surge of power or a cable comes loose, the engaged parking brakes can help prevent the vehicles from moving unexpectedly.
- Peace of Mind:
Knowing that both vehicles are securely held in place by the parking brakes gives you peace of mind and allows you to focus on the jump-starting process without worrying about the vehicles moving.
Therefore, always remember to engage the parking brakes on both vehicles before connecting the jumper cables. This simple step contributes to a safe and successful jump-start experience.
Connect red to positive (+).
When connecting the jumper cables, it's crucial to start with the positive (+) terminals on both batteries. Here's why:
- Positive Terminal Identification:
Positive terminals on batteries are typically marked with a "+" symbol, the color red, or both. Look for these indicators to ensure you're connecting the red jumper cable to the positive terminal.
- Power Source:
The positive terminal of the working car's battery is the source of power that will jump-start the dead car. Connecting the red jumper cable to this terminal ensures that power flows from the working battery to the dead battery.
- Safety First:
Connecting the red cable to the positive terminal first helps prevent accidental sparks or short circuits. This is because the positive terminal is typically located away from other metal components in the engine compartment, reducing the risk of contact with grounded surfaces.
- Industry Standard:
Connecting the red cable to the positive terminal is the industry standard for jump-starting vehicles. Following this convention ensures consistency and reduces the likelihood of mistakes.
Therefore, always start by connecting the red jumper cable to the positive (+) terminal on the dead car's battery, followed by the positive terminal on the working car's battery. This ensures a safe and proper connection for jump-starting.
Connect black to negative (-).
Once the red jumper cable is securely connected to the positive terminals, it's time to connect the black jumper cable to the negative terminals on both batteries. Here are the reasons why:
- Negative Terminal Identification:
Negative terminals on batteries are typically marked with a "-" symbol, the color black, or both. Look for these indicators to ensure you're connecting the black jumper cable to the negative terminal.
- Completing the Circuit:
The negative terminal of the battery completes the electrical circuit, allowing the current to flow from the working battery to the dead battery. Without a proper connection to the negative terminal, the jump-start process won't be successful.
- Safety Precaution:
Connecting the black cable to the negative terminal last helps prevent sparks or short circuits. This is because the negative terminal is typically connected to the chassis or engine block, which acts as a ground. By connecting the black cable last, you minimize the risk of accidental contact with other metal components.
- Industry Standard:
Connecting the black cable to the negative terminal is the industry standard for jump-starting vehicles. Following this convention ensures consistency and reduces the likelihood of errors.
Therefore, after connecting the red cable to the positive terminals, connect the black jumper cable to the negative terminal on the dead car's battery, followed by the negative terminal on the working car's battery. This completes the electrical circuit and allows the jump-start process to be successful.
