What happens when the belt on an alternator breaks?
A closer observation of the alternator will reveal a pulley and belt system that works to convert mechanical energy into electrical energy. The serpentine belt powers the alternator, and if it fails, the alternator will stop working the moment your belt wears out and breaks, or the pulley becomes damaged.
What should I do if my alternator is not working?
The solution is to check your car’s manual for the particular fuse that controls the alternator and replace it. In some cars, you might also find another small fuse to the alternator’s control—usually a 15A to 20A fuse. An alternator does usually has 3 or 4 wires to it to function properly.
Why does a battery need an alternator to work?
The battery cannot supply all this power on its own, hence the need for the alternator. The alternator converts mechanical energy into electricity. The alternator is connected to a set of belts which when loose can cause it not to function as required.
Why is the serpentine belt on my car not working?
This can also happen if the serpentine belt is not tightened correctly. Most cars have automatic tensioners, but these can fail, so it is better to double-check.

Why does my alternator belt not go down?
During the measurement of the belt slack, it the belt does not go down ½ inch, you will have to release tension off the tensioner bolt. A tighter belt can even be a result of the belt being smaller than what is required around the alternator.
How is the alternator belt connected to the crankshaft?
There is something called an alternator belt (also called a serpentine belt) which wraps around a pulley or multiple pullies that is connected to the alternator. The other end of the pulley wraps around the crankshaft. Therefore, the crankshaft and alternator are able to rotate together by the alternator pulley.

Manufacturers recommend the belt to be replaced every 40,000 to 50,000 miles. However, note that you need to get it replaced as soon as you encounter any problems mentioned above. Sometimes, frequent loosening of a belt is also the fault of the tensioner, which is when you need to get the tensioner replaced.
How can I tell if I have an alternator problem?
To differentiate an alternator problem from the battery, you will need to use a voltmeter to check for voltage. First, turn off the engine and check the battery voltage. A fully charged battery should have a reading of 12.65 volts. Next, turn on the engine and recheck the voltage. You should have a reading of 13.5 to 14.5 volts.
How do you remove an alternator from a car?
If your vehicle does not have an auto tensioner, insert a pry bar or piece of wood between the alternator and the engine. Run the belt over the alternator pulley, then use the bar to pry the alternator away from the engine and increase the tension on the belt.
