Alternators

Refine Results

It is the job of your alternator to charge the battery and power the electrical systems in your BMW. The other electrical systems the alternator helps to regulate include your lighting and things like your power windows. The battery in your vehicle is not able to provide power to these systems as it does not have enough to stay charged and do so. For your car to be able to get all the power it needs, it's important to keep your alternator running smoothly. This can be done by performing regular maintenance on your vehicle and checking the condition of the alternator often. It also helps to know what some signs are that your alternator is failing so you can get it repaired sooner versus later. One of the biggest signs that something might be wrong is reduced power on the road. Things like your power windows or your radio might start to struggle to function as well as they used to. Dashboard or headlights might start to flicker or become dim. Your battery can also start to have performance issues when the alternator is dying. It's important to check both of these parts to determine what is actually wearing out. Find OEM BMW alternators here when needed.
