What happened to the sudden power failure of the car?

What happened to the sudden power failure of the car? The reasons for the sudden power failure of the car are as follows: 1. Maybe the battery is dead. First, check the car battery to see if it has electricity. If the battery charge is normal, you need to check the ignition system and starting system of the car. If the battery is dead, it should be replenished in time. Under normal circumstances, the battery can be used for 3 to 5 years. In the process of using the car, you must always pay attention to the battery charge. Turn off the function of the car in time after parking to avoid sudden power failure of the battery. In addition, the power failure of the car may also be due to GPS problems, so you can go to the place where GPS is installed for maintenance. 3. Wrong wiring or poor grounding of the burglar alarm will also lead to power failure of the car. 4. There is something wrong with the fuse box itself or the connection part of the wire harness plug connected to the fuse box. You can check whether the pins on the fuse box socket are not firmly in contact with the circuit in the fuse box, and whether the circlip on the wire harness plug is loose. @20 19
