* The battery powers the starter: When you turn the key, the battery provides the initial power to crank the engine.
* The alternator recharges the battery: Once the engine is running, the alternator takes over and generates electricity to recharge the battery and power the car's electrical system.
If the alternator is faulty:
* The battery will gradually drain: Without the alternator recharging it, the battery will lose power.
* Eventually, the car will die: Once the battery's charge is depleted, the car will not be able to start again.
Here's a breakdown of what might happen:
* A car can start with a bad alternator, but the battery will not get charged.
* The car will run for a while, depending on the battery's charge level.
* The electrical system will begin to malfunction as the battery drains.
* Eventually, the car will stall completely.
Important Note: While a car can start with a faulty alternator, it's very dangerous to continue driving with a bad alternator. It can cause significant damage to your car's electrical system, potentially leading to a breakdown while you're on the road.
If you suspect your alternator is faulty, get it checked out by a mechanic as soon as possible.
