Why does the car battery light come on when wading through water?
1 Answers
Car wading battery light is the battery charging indicator light, which is caused by the generator getting wet when crossing water and causing a temporary short circuit that stops it from generating electricity. It can be used safely after the water dries. 1. The reasons why the car indicator light comes on are as follows: After the vehicle wades through water, if the water is deep or the speed is fast, causing water to splash onto the belt, it will cause the belt to slip, and the generator will temporarily stop working, so the battery light will come on. After leaving the deep water area or when the water on the belt is dried, it can continue to be used. 2. Precautions for driving through water: When driving on waterlogged roads, you should first ensure that the vehicle has stable and powerful power to keep the exhaust pipe filled with pressure gas to prevent water from flowing back into the exhaust pipe and causing the engine to stall. During driving, try to maintain a low gear and steady speed, avoiding stopping, shifting gears, or turning the steering wheel sharply. If the car stalls in the water, it means that the engine has already been damaged by water. At this time, if you continue to try to start the car, it may cause the engine's piston to seize or break, causing fatal damage to the engine.
