Can an Alternator Go Bad From Sitting?
It is possible for an alternator to go bad from sitting for an extended period. However, the likelihood of this happening depends on various factors, such as the age and condition of the alternator, the storage environment, and the length of time it sits.
An alternator is a critical component of a vehicle’s electrical system that converts mechanical energy into electrical energy. It generates power to charge the battery and run the car’s electrical systems while the engine is running. When the engine is not running, the alternator is not producing electricity, and the battery takes over to power the electrical systems.
If an alternator sits idle for an extended period, its internal components can deteriorate, and various problems can arise. For instance, the alternator’s slip rings can corrode, leading to poor electrical conductivity and voltage regulation issues.
Also, the bearings that support the rotor shaft can dry out and cause increased resistance and wear, leading to premature failure. Additionally, the brushes that make contact with the slip rings can wear down and fail to provide sufficient electrical contact.
The likelihood of an alternator going bad from sitting also depends on the storage environment. Extreme temperatures and high humidity can accelerate corrosion and other forms of degradation in the alternator’s internal components. Ideally, the alternator should be stored in a cool, dry place to prevent moisture and other contaminants from affecting its performance.
Finally, the length of time an alternator sits can also affect its performance. If an alternator sits idle for a few months, it may not have any significant impact on its performance. However, if it sits idle for several years, it is more likely to suffer from corrosion, rust, and other forms of deterioration that can affect its performance.
In summary, while it is possible for an alternator to go bad from sitting for an extended period, the likelihood of this happening depends on several factors. To avoid potential issues, it is best to store the alternator in a cool, dry place and periodically inspect it for signs of corrosion or wear.

How Sitting Can Affect Specific Components of an Alternator
When an alternator sits for an extended period, several of its components can be affected, including the slip rings, bearings, and brushes.
Slip Rings
Slip rings are a crucial component of an alternator that help to transfer the electrical current from the rotor to the external circuit. When an alternator sits for a long time, the slip rings can become corroded due to exposure to moisture and other environmental factors. Corrosion can lead to poor electrical connections, which can result in reduced performance or even failure of the alternator.
Bearings
Bearings help to support the moving parts of an alternator, such as the rotor and pulley.
