How to correctly connect a jumper cable is good to know if your vehicle can not start due to a dead battery. The cable connects to the car battery of the second car and then recharges your car’s battery. But how exactly does the bridging happen? Read more in this article.
Car battery empty: connect the jumper cable
- There are many causes of a weak battery. These include, for example, own negligence. For example, if you forget to turn off the light when parking, the battery will be charged during standstill and maybe empty the next time you start it.
- Or the vehicle’s alternator has a defect that can cause the battery to drain.
- Also, cold weather can be a cause of a weak battery.
- And if your car has an old battery, it can also quickly lose energy. But with a second vehicle, the energy can be easily recharged.
What must preparations be made for bridging?
- the car radio
- the lighting of the interior
- the headlights
- If you are in a non-hazardous location, you can also turn off the hazard warning lights on the cars.
- Finally, you must also turn off the engine and apply the handbrake. For automatic cars, uses Park gang insert. With the manual gearbox, you should go to idle.
Pay attention to a few things when connecting the jumper cable to the car battery.
- Which cable to connect to which pole
- Which vehicle will be started first
- Remove the jumper cable
- What do you have to look out for in the batteries before the jump start
- What do you do after the successful jump start
Follow the given order. Connecting the right one prevents expensive damage. It is very beneficial if you always have a jumper cable in your trunk. You never know, you become a helper or needed to help themselves.
Connect the jumper cable correctly – this is how you find the positive pole.
- Now look in the engine compartment for the car battery and check the poles for possible contamination by rust or similar. If necessary, cleansing may be enough to get the car started again.
- If this is not the case, you must clamp the red part of the jumper cable to the positive pole of the battery. It may be necessary to remove a cover beforehand. The positive pole is usually marked with a plus sign. They also recognize him by the red cables that lead to it. The second red terminal is intended for the positive pole of the battery of the second car. Attach these also firmly.
- Check that the batteries of both vehicles, donor and receiver, have the same voltage. The usual is 12 volts. The tension of the donor should not be much smaller in comparison.
- Switch off redundant energy consumers, for example, heating and radio, in both participating vehicles.
- Connect the red cable to the positive pole of the receiver and only then to the positive pole of the dispenser.
- Connect the black jumper cable to the negative donor terminal and then to a metal part of the receiver vehicle. For safety reasons, never connect directly to the negative pole of the receiving battery!
- First, start the donor and then the receiver vehicle.
- Switch on one or more energy consumers in the receiver vehicle to protect the electronics from impending overvoltages.
- If the battery is deeply discharged, leave the jumper cables connected for at least 10 minutes to ensure optimal charging.
- First, remove the clamp on the ground (metal part) of the receiver, then in any order, all other contacts.
- Switch off the power consumers at the receiver and drive the car for at least an hour to charge the battery. If everything goes well, your vehicle should be ready to go!
When connecting the jumper cable, attach the black terminals.
- The black terminals of the cable are mounted on the negative terminal of the battery of the second vehicle—the remaining terminal you need for the so-called grounding.
- Position the clamp on a metal surface for this purpose. You should pay attention to a firm attachment so that the clamp does not come loose when the motor vibrates.
