What Signs Show that Car Alternator Brushes are Worn (+Can you Replace them)?

There is a good chance that your alternator’s brushes are worn if you have narrowed down the problem with your car’s electrical system to the alternator, ruled out both weak cable connections in the electrical system, a bad battery, and the alternator been in service for several hundred thousand miles.
How long the car alternator brushes last depends on the quality of the alternator build and to a certain extent whether is a new OEM alternator or a refurbished alternator.
Some car owners have replaced them at about 170,000 miles mark while others have done 250,000 miles + without replacing them.
If in doubt contact a qualified auto mechanic for assistance.
