What Causes a Car Not to Start in the Rain?

There may be water leakage causing a short circuit in the ignition coil—simply drying it off should resolve the issue. In low temperatures, the battery's electrolyte viscosity increases, reducing its permeability and increasing resistance, which lowers the output power. This makes it difficult for the starter to crank the engine to the minimum starting speed, affecting engine ignition. Additionally, low battery voltage results in weak spark plug sparks, and the increased resistance between electrodes due to higher mixture density makes it harder to ignite the fuel-air mixture. Below are some precautions for car battery usage: 1. Always turn off lights: For example, forgetting to turn off headlights during the day, especially for beginners who may leave car lights on after playing with the vehicle, can drain the battery over time. Similarly, listening to music or using the air conditioning without the engine running can also deplete the battery. 2. Pay attention to maintenance: To prevent battery drainage, proper maintenance is essential. Avoid frequent engine starts—cars have their limits, and repeated starting can cause wear. If the car doesn't start on the first attempt, wait a moment before trying again. Continuous starting puts significant stress on the car, increases discharge, and gradually shortens the battery's lifespan.
