The correct connection method of booster cable mainly includes the following steps:
1. Make sure both vehicles are turned off and all unnecessary lights and accessories are turned off to avoid electrical accidents.
2. Open the engine compartment cover. If the battery has a protective cover, you need to remove the protective cover to expose the positive and negative terminals of the battery.
3. Confirm the positive and negative poles of the battery. If you cannot tell the difference, do not start charging.
4. Use a red connecting wire, connect one end to the positive terminal of the rescue vehicle, and the other end to the positive terminal of the rescued vehicle.
5. Use a black connecting wire, connect one end to the negative terminal of the rescue vehicle, and the other end to the negative terminal of the rescued vehicle or the body.
6. After connecting the lines, start the engine of the rescue vehicle, and then start the engine of the rescued vehicle.
After starting the vehicle, remove the cables in reverse order.
7. It should be noted that when connecting the battery cable, the positive pole should be connected first and then the negative pole. This order is to prevent accidental short circuit. At the same time, disassembly should also be carried out in this order. During operation, the positive and negative poles must not come into contact, otherwise it may cause a short circuit or even a fire.
