The Best BMW Alternators

Refine Results

The electrical systems in your BMW have to be powered some way. While your battery helps to power parts of your vehicle, it doesn't have enough juice to keep things running all day. This is where your alternator comes in. The alternator not only helps to recharge your battery but keep other systems in your vehicle charged as well, including things like your lights and power windows. If you experience issues with your alternator, there is a lot that will be affected. It's important to pay attention to signs that something might be going wrong with your alternator. Weakened performance can be one of the biggest signs something is wrong with the part. You might notice that things like your radio or power windows are struggling to operate at the power that you're used to. You also might notice your headlights or dashboard lights becoming dim or flickering if there is a problem with your alternator. The alternator dying can also cause your battery to have performance issues. You need to to make sure to replace your alternator when you notice signs of problems so your car can still operate effectively.
