Will your lights come on if alternator is bad?

It is possible for your lights to come on even if your alternator is bad. This is because your car's battery can still provide power to the lights, even if the alternator is not working. However, the lights will eventually dim and go out if the alternator is not replaced.

The alternator is responsible for charging the battery and providing power to the electrical system in your car. If the alternator fails, the battery will eventually drain and the car will no longer be able to run.

Here are some signs that your alternator may be bad:

* The battery warning light comes on.

* The lights dim or flicker.

* The car stalls or hesitates when you accelerate.

* The engine overheats.

* The battery is dead or does not hold a charge.

If you experience any of these symptoms, it is important to have your car checked by a mechanic as soon as possible. A bad alternator can cause serious problems with your car's electrical system and can even lead to a fire.
