Alternators are a crucial part of your car or truck electrical system. If the alternator is not working, you will need to replace it or have it rebuilt.
When a car alternator is not working, there are many things that can cause this issue. It could be the wire that connects the alternator to the battery, the brushes that turn on and off in order to charge your battery or even something as simple as a dirty terminal connection.
Replacing or rebuilding an alternator takes skill and patience, if you are unsure about what might be wrong with your car's alternators or how to fix them, it is best to leave it up to an expert who has years of experience in auto repair.
