Yes, a car can go dead, meaning it can completely lose power and become inoperable.
This typically happens when the car's battery is drained and the alternator, which is responsible for recharging the battery while the engine is running, fails to keep the battery charged. Here's a more detailed breakdown:
-
Battery Failure: The car battery provides the initial power to start the engine and run electrical components. If the battery is old, damaged, or not properly charged, it can lose its ability to hold a charge, leading to a "dead" car.
-
Alternator Problems: The alternator recharges the battery while the engine is running. If the alternator malfunctions, it won't recharge the battery adequately. Over time, the battery will drain, and eventually, the car will stall or won't start at all. As the quoted text states: "if the alternator isn't functioning properly and the battery dies, your car may eventually lose power and stall or completely shut off."
-
Parasitic Drain: Even when the car is off, certain electrical components (like the alarm system or the car's computer) continue to draw a small amount of power from the battery. If there's an excessive parasitic drain (e.g., a light left on, faulty wiring), it can deplete the battery over time.
-
Other Electrical Issues: Short circuits, damaged wiring, or faulty electrical components can also cause the car to lose power and "die."
Therefore, while the battery is often the first suspect when a car won't start, a dead car can be the result of a combination of factors affecting the battery and the charging system.
