📚 What is Alternator Repair?
Alternator repair involves fixing specific components of the alternator to restore its functionality. This is typically done when only certain parts, like the voltage regulator, brushes, or bearings, are faulty. Repairing can be a cost-effective solution if the main structure of the alternator is still in good condition.

🛠️ What is Alternator Replacement?
Alternator replacement means removing the entire old alternator and installing a new or remanufactured one. This is usually the preferred option when the alternator has significant internal damage, such as a shorted stator or rotor, or when it's simply reached the end of its lifespan. Replacing ensures a reliable and long-term solution.
