What does the car plus-minus light indicate as a fault?
1 Answers
When the car plus-minus light is on, it indicates that the generator's output voltage is lower than the battery voltage, the generator is not working, or there is a fault in the power supply circuit. At this time, the vehicle is running on battery power, and you should go to a repair shop as soon as possible to check the generator, charging circuit, and all batteries. Like all batteries, if not charged, the car's battery will eventually run out of power, causing the car to fail to operate normally. Common car fault lights include the following: 1. Tire pressure warning light: A yellow symbol, an irregular circle with an unsealed top and four small spikes at the bottom, with an exclamation mark inside. When this symbol appears, it means the tire pressure is abnormal, and the tires should be checked promptly. 2. Water temperature indicator light: This light usually stays on when the car is first started, especially in winter. It has a blue thermometer-like shape and will light up if the water temperature is too high or too low. Some vehicles have a temperature gauge on the dashboard, with a pointer that rises or falls with the water temperature. If the water temperature is too high, stop driving immediately and wait until the water temperature returns to normal before going to the nearest 4S shop or auto repair shop for inspection.
