Why does the car's instrument pointer swing violently when starting?

[LeahRose]

The reason why the car's instrument pointer swings violently when starting is that the battery is low on power. One situation is that there were power-consuming items left on when the car was last turned off, such as lights or the radio, which caused the battery to drain. You can ask someone for a jump start, and the battery will recharge after the car starts. Another situation is that the battery is damaged. A jump start is only a temporary solution, and it's best to replace the battery. The instrument panel can be equipped with external lighting and can also be attached to a console. It comes in various forms and specifications, allowing for the installation of various instruments as needed, or combining various instrument panels into a single unit as required. The car instrument panel is a device that reflects the working conditions of various vehicle systems. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights.
