Why Does a Car Lose Power When It Rains?

[McIvan]

Rain can cause a car to lose power possibly due to aging wires leading to short circuits in wet conditions, thereby increasing the battery's self-discharge. It is advisable to check the car's wiring. Additional Information: If the car battery is dead, you can seek assistance from another vehicle to jump-start the engine. Once the engine is running, the alternator will operate, allowing the battery to recharge. When a car is left unused for an extended period, the battery will self-discharge, potentially leaving it without power when you next try to use the car, making it impossible to start the engine. For long-term storage, you can disconnect the battery's negative terminal. During regular maintenance, have a technician use professional equipment to test the battery's internal resistance and voltage. If the voltage and internal resistance do not meet standard values, it indicates that the battery needs replacement.
