Many owners of old cars may encounter this problem. If their car fails to start normally, the first thing they think about is that the battery is dead. What can be done to solve this problem? Today, let's talk about how to solve this problem by wiring.
First of all, we need to do some preparatory work to ensure the correct and safe conduct of the subsequent power on, first turn off the radio, air conditioning, headlight and other electrical equipment in the car.
If there are insulating gloves on the car, please put on the gloves and go to do the next work. Although the voltage of the vehicle battery is mostly 12V, it will not kill people, but I'm not afraid of ten thousand. In case of an accident, I regret it too late. Even if there is no, the dry rag can be used instead, but it must be completely dry! Confirm whether the vehicle battery is at the front or the rear of the vehicle, and ensure that the distance between the two vehicles can be enough to connect the wires.
As we all know, batteries have positive and negative electrodes. Generally speaking, the positive electrodes on the batteries are covered with red protective covers, and there are also black ones with a "+" symbol on them. The other end is the negative electrode. Generally speaking, there is no protective sleeve for the negative electrode, which is easy to distinguish. The voltage of vehicle battery is mostly 12V, and the normal life is 3-5 years.
The grounding wires are both red and black, with the red connecting the positive pole and the black connecting the negative pole. There are various types of wiring in the market, some expensive, some affordable, but whether it is affordable or expensive, the quality is not necessarily good. If you want to buy grounding wires, you must buy Copper ones. As we all know, copper's conductivity is second only to silver. Therefore, you need to bear hundreds of amperes of current in a moment. Without good materials, you can't do it. More importantly, from the safety point of view, the clamp with more than one hundred yuan is covered with soft adhesive, which greatly reduces the possibility of electric shock.
It's not difficult to take a ride. As long as you don't make mistakes between the positive and negative poles and short circuit the positive and negative poles. Remember that the positive pole is to the positive pole, and the negative pole to the negative pole. As a car owner, you need to know and master how to operate. When choosing the cable, try to choose more than one hundred yuan. The quality and safety of these grounding wires are guaranteed. After all, the raw material price of copper is not cheap.
