Less Energy Supply

An alternator’s foremost problem which can generate other problems in different places is the less energy supply. It is most frequent as 2001 Nissan Xterra alternator problems and causes blown headlights or other electrical equipment.

Burned Belt

Another frequent problem is the belt burn that establishes the connection between the crankshaft and the alternator’s rotor shaft.

This problem can also occur if the belt becomes loose. It can not create a proper grip and start burning due to the rotation. With the burning odor, you can also notice the annoying sound of the belt.


If you face such a problem, you must immediately open your bonnet. Since the problem generally rises from the loose belt, if you take action immediately, you can avoid the eventual burn of the belt.

An alternator is nothing but a machine. It has a complex internal design. Due to the heavy and long time use, it can break down anytime. However, you can determine the breakdown quickly.


The symptoms of a dead alternator are pretty simple. The first symptom is no ignition. When you ignite the engine, it will take charge of the battery and start for a few seconds. After that, the engine will stop working.

#4. Internal damage to the alternator due to obstacles

Will a car run with a bad alternator?

No, a car can’t run for a single moment with a bad alternator. Generally, when a car engine runs, it rotates the crankshaft. And a belt establishes a connection between the crankshaft and rotor of the alternator.
