Hello,
There are many symptoms of a bad alternator that you should pay attention to:
If your alternator is not working properly it might affect how the alternator belt is turning. An alternator that is not working properly will make an audible sound. Removing the alternator belt can confirm if noise is coming from the alternator.
Another symptom is if anything electrical slows (windows, seats, etc) or the lights dim while you are driving.
Yet another symptom is experiencing difficulties starting your car. This could be an issue with the battery, so make sure that you check the terminals and note the age of the battery. If your battery frequently discharges then this is another sign of a bad alternator.
Hope this helps!
