Bad Alternator

Alternators are part and parcel in charging the battery. The component is often long-lasting and reliable. Nevertheless, like any electrical element, an alternator might have errors over time.

The bad alternator might cause a big trouble for its voltage regulator which manages the power quantity that comes into the car charging system.

When the part is defective, it won’t charge the battery properly, causing your vehicle to stall due to a lack of power.

Dead Battery

This is one of the key roots of charging system rupture in an automobile. For example, if your vehicle is pretty old (over five years old), it might be out of order to charge properly.

So there is a high chance that the battery is dead and requires replacement.

Using a battery test is a great solution to discover whether the battery is still in normal condition or stuck in a problem.

If the test’s result is alright yet the warning is still on, then the issue might be on other parts.
