What does the positive and negative sign on the dashboard mean?

When the dashboard displays battery positive and negative signs, it indicates that the generator is not working, and the battery power will be quickly depleted as it cannot be replenished. Below is an introduction to the dashboard: 1. Introduction: The car dashboard is a device that reflects the working conditions of various vehicle systems. 2. Types of indicator lights: coolant level warning light, fuel level indicator, washer fluid level indicator, charging indicator, high/low beam indicator, transmission gear indicator, anti-lock braking system (ABS) indicator, traction control indicator, airbag (SRS) warning light, etc.
I remember the first time I drove when that battery icon with positive and negative symbols lit up on the dashboard - I got really nervous. It meant there was a fault in the car's charging system, possibly the alternator wasn't working or the battery itself had issues. I was on a suburban road at the time, the AC suddenly stopped cooling, and the lights dimmed. I immediately drove slowly to a nearby repair shop. The mechanic found it was caused by a loose alternator belt preventing charging. If ignored, the battery would drain quickly, potentially causing the car to stall midway or even increasing accident risks at night. Since then, I've developed the habit of checking dashboard lights and engine compartment belts monthly for abnormalities, and haven't had similar troubles since. Remember, never delay dealing with such issues - they concern overall driving safety.
