What’s the reason for the sudden loss of electricity in the car?The battery is dead without warning

Sudden power failure of the car will have two states. The first is that the car still has some electricity, but all functions are unavailable, and the car dashboard will light up. The second state is that the car has no reaction at all, and the car has no electricity in the whole car, and the battery needs to be recharged in time before it can be used normally. When the car is powered off, car friends can judge the cause based on the above two states. Let's talk about how to troubleshoot it below.

First, check the battery of the vehicle to see if the battery is charged. If the battery is normal, you need to check the ignition system and starter system of the car. If the battery is losing power, you need to replenish the battery 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's power. After parking, turn off the function of the car in time to avoid sudden loss of power to the battery.

In addition, the power failure of the car may also be caused by GPS. You can go to the place where the GPS is installed for maintenance. Incorrect wiring of the anti-theft device or poor grounding can also cause the car to power off. Otherwise, there is a problem 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 and the circuit inside the fuse box are not in contact with each other, and whether the card spring on the wire harness plug is loose.
