Which alternator do I need?

To determine which alternator you need, you'll need to consider your vehicle's make and model, engine size, and electrical system requirements. You can typically find this information in your vehicle's owner's manual or by consulting a qualified mechanic. Additionally, you'll need to consider the amperage output of the alternator, which refers to the amount of electrical power it can produce. This will depend on the electrical demands of your vehicle and any aftermarket accessories you may have installed, such as high-powered audio systems or off-road lighting.
