If your car’s battery has died, jump starting it can be an effective and simple way of rejuvenating it. But for safety purposes it’s essential that you learn how to do this safely.
To jump start your car, a set of jump leads is essential. These cables feature fully insulated alligator clips with clear polarity markings and sturdy clamps made from copper or copper-clad aluminum material.
1. Connect the Jumper Cables
Every driver knows the frustration of turning their key or pressing the start button and nothing happening. A dead battery could be to blame here, but jumper cables may help bring it back to life so that you can get back on the road as soon as possible.
To prevent damage to either your battery or car electrical components, invest in jumper cables with metal clamps equipped with safety guards that are insulated for added insulation and include carrying bags that keep cables organized and safe from damage.
Help yourself by having someone connect the positive cable end to the terminal marked “positive” on the dead battery and the other to an engine block metal ground of the car assisting you. Be sure that both vehicles are close enough together that both cables reach without touching each other; turn off its engine when finished and take any necessary actions to return power to both vehicles.
2. Turn Off the Engine
Jump starting a car may appear miraculous when it works, but its science is fairly simple. Simply put, current from one battery travels through to start the engine in the other battery that had died.
Before jumping in, make sure both vehicles’ engines are shut off and keys removed, and park the donor car as close to your Toyota as possible (nose-to-nose or side-by-side but without touching) so the jumper cables can reach both batteries. Open up its bonnet (or boot, depending on where it’s housed) to identify batteries; they usually have red covers with either a “+” or ‘-” symbol on them.
Attach one end of the red cable to the positive terminal on a dead battery and use a prying tool to carefully pry away any plastic covers or corrosion to expose its terminals. Wear gloves as this may prevent sparking from occurring.
3. Connect the Positive Cable
An efficient jump start may be all it takes to revive a dead car battery and get you driving again, but it’s essential that you follow some safety measures prior and after using jumper cables.
Position the working car alongside its dead counterpart — without touching them — then switch off their ignitions in both cars. Dead batteries typically feature red positive terminals marked with plus and minus symbols; when necessary, use a flashlight or mirror to help illuminate both terminals if they become dirty.
Secure one end of a red cable clamp to the positive terminal on a dead battery and the other end to metal part on a working car chassis. As soon as the engine starts in the problem car, disconnect cables in reverse order starting with black negative cable at grounding metal on dead battery and ending with red positive cable on working car chassis.
4. Connect the Negative Cable
Jump-starting a car requires more than simply connecting cables and revving up its engine; the process involves positioning both vehicles correctly, securing cables in their proper places, and safely disconnecting them once your engine starts up.
Position the working car close enough to the dead battery without them touching, but far enough apart that they don’t come into contact. Switch off both engines and accessories; set the parking brakes; raise both hoods to access batteries. Locate the dead car’s positive terminal – usually red with an “+” symbol – on its positive terminal while the working battery has its negative terminal marked with “-“.
Attach the black negative cable from your booster to the dead car’s battery’s negative terminal and connect its other end to a ground point on either its engine block or another metal surface far from its battery.
5. Start the Working Car
Jump-starting a car should be easy and safe when following the right steps. To prevent potential damage from using cables or portable jump starters incorrectly. In addition, make sure that your battery remains healthy by performing periodic tests (especially before hot or cold weather arrives) as well as testing it twice annually – testing twice annually may even save on replacement costs!
Basic troubleshooting steps may also help:
- Identify some potential reasons for a car not starting
- Placing it into Park or Neutral and checking its fuel gauge
- Checking stereo system output and looking for dimming lights
- Issues with stereo output or smells of burning wires or rubber which could indicate issues with either battery
- Alternator or ignition systems that require professional intervention.
If these measures do not resolve your issue call roadside assistance so a technician can diagnose any problems and suggest solutions.
6. Remove the Jumper Cables
An experience with a dead battery can be both time consuming and distressing, so learning to jump start your car safely is crucial to avoid unnecessary disruption and unnecessary frustration. By following these simple steps and taking necessary precautions, you can safely jump start your car quickly and effortlessly.
Once the engine of the working car is running, remove the black clamp from the negative terminal on the dead battery and disconnect it from its grounding point (usually an unpainted metal piece) on its body to avoid sparks that could potentially harm computers and electrical systems in both cars.
Keep jumper cables handy at all times in case your car won’t start! However, if it seems that its battery has been failing frequently and frequently needs charging up or replacing then perhaps its time to visit one of our locations for professional inspection and replacement service.
