Why is the car not getting power?
1 Answers
Introduction to the reasons why a car is not getting power: The entire car not getting power may be due to a blown main fuse, a dead battery, or circuit issues. Below are the specific details and solutions: 1. If the screen is completely black and does not turn on, check if the car's original fuse is blown. If the fuse is blown, replace it. 2. Check if the navigation buttons are stuck, including the RSET button. Stuck buttons can also prevent the system from turning on. If skilled, you can remove the navigation unit and check if the tail fuse of the navigation is blown. If it is blown, replace it. 3. If the screen is black and does not turn on, use a multimeter to measure whether the B+ and ACC voltages are normal (12V). If the voltage is normal, then the issue is an internal fault of the device and requires opening it for repair.
