Alternators

In modern vehicles, alternators are used to recharge the battery and power a running electrical engine. Until recently, cars in the 21st century often used generators to charge the battery. The primary purpose of the alternator as a part of the electrical system in a car is to provide power to run the ignition and starter. A symptom of a weak alternator will be noticeable when the dashboard lights or headlights become dim. Sometimes an ‘ALT’ warning light will show up. Make sure you replace your alternator if it wears out, so no major issues occur with other parts down the line.
