Will a Car's Generator Be Damaged When Driving Through Water?

[DelIker]

Water entering a car's generator will not cause immediate damage, but it can affect the engine's lifespan. It is recommended that car owners take protective measures. The generator is an electrical component containing stator windings and rotor coils. Related information about generators: Function: The car generator serves as the primary power source, supplying electricity to all electrical devices (except the starter) while the engine is running normally and simultaneously charging the battery. Composition: Due to the superiority of AC generators in many aspects, DC generators have been phased out. AC generators generally consist of four parts: the rotor, stator, rectifier, and end cover.

Last year, my car's alternator was damaged after driving through deep water. During heavy rain, the road was flooded, and I forced my way through, causing water to enter the engine compartment and submerge the alternator. The next day, the charging light stayed on when I started the car, and later inspection revealed an internal short circuit had burned it out. The mechanic said alternators aren't waterproof, and if water depth exceeds half the tire height, there's a high risk of water ingress corroding the circuits. The only repair option was a costly replacement. Now, I avoid puddles altogether and promptly dry the engine compartment after any water exposure to minimize damage.

Whether the generator gets damaged during water wading mainly depends on the water depth that could cause it to short-circuit by water ingress. Since the generator is positioned low and generally not well-sealed, water levels exceeding the chassis may allow water to enter, burning out the coils or components. After wading, drive slowly to avoid splashing water too high, then promptly check the dashboard for any abnormalities and seek repairs without delay to prevent more significant issues. Controlling water depth is the key to preventing damage.

Yo, will a generator get damaged when wading through water? Absolutely! If the water is deep enough to submerge it, it'll short-circuit and burn out. Like when my car skidded through a puddle before, the charging system just crashed straight away. The repair costs were crazy expensive. So when driving, steer clear of puddles and don't take the risk. After wading through water, always do a thorough check—safety first! Don't let water wreck your car.
