The Ultimate Guide to Buying an Alternator
Overview
An alternator is a crucial component of your car's electrical system that helps keep the battery charged and powers the electrical accessories. If your alternator is failing or has failed, it's essential to replace it as soon as possible to avoid further damage to your car's electrical system.
In this guide, we'll walk you through the different types of alternators, key considerations when choosing one, important features to look for, prices, tips, and FAQs.
Types
1. Standard Alternators: These are the most common type of alternators and are designed to work with most vehicles. They come in various sizes and output capacities, so it's essential to choose the right one for your car.
2. High-Output Alternators: If you have a lot of electrical accessories in your car, such as a high-powered sound system or off-road lights, you may need a high-output alternator. These alternators can produce more power than standard alternators and are designed to handle the extra load.
3. Remanufactured Alternators: Remanufactured alternators are rebuilt from used parts and can be a cost-effective option. However, it's essential to choose a reputable supplier to ensure the alternator is of good quality.
Key Considerations
1. Compatibility: The alternator you choose must be compatible with your car's make and model. Check your car's manual or consult with a mechanic to ensure you're choosing the right alternator.
2. Output: The alternator's output determines how much power it can produce. Choose an alternator with an output capacity that meets your car's needs.
3. Brand: Choose a reputable brand with a good track record for quality and reliability.
Features
1. Voltage Regulator: The voltage regulator helps regulate the alternator's output voltage, ensuring it stays within safe levels.
2. Diode Rectifier: The diode rectifier converts the alternator's AC output to DC, which is what your car's electrical system uses.
3. Bearings: The alternator's bearings help reduce friction and ensure smooth operation.
Prices
The price of an alternator varies depending on the type, brand, and output capacity. Standard alternators can cost anywhere from $100 to $300, while high-output alternators can cost upwards of $500. Remanufactured alternators can be a more affordable option, costing between $50 and $200.
Tips
1. Check your car's battery before replacing the alternator. A failing battery can cause issues that mimic alternator problems.
2. Choose a reputable supplier when buying a remanufactured alternator.
3. Consider upgrading to a high-output alternator if you have a lot of electrical accessories in your car.
