Your BMW’s alternator should generate between 13 volts and 14.5 volts. This voltage is used to produce electricity to power numerous things. This includes keeping the battery charged as it discharges. Kinetech Motor Werkes can replace your alternator when it needs it. Here are signs that it does.
Light Problems
Perhaps the most noticeable sign that your alternator is going bad is problems with your BMW’s lights. For example, you may notice that all of the lights, including the headlights and interior lights, are too dim. They may also flicker or be abnormally bright. This is an indication that they aren’t getting the proper amount of voltage in a steady stream.
Accessory Problems
A faulty alternator can also affect your BMW’s accessories. For example, if the alternator is not producing the normal amount of voltage, your power seats and windows may slow down significantly. Other power accessories may not work at all.
Battery Problems
As we mentioned above, the alternator keeps the battery charged so it always provides the necessary power to start and run your automobile. A dead battery that does not retain a charge is a sign that the alternator is not charging the battery as it discharges.
Frequent Stalling
The alternator also provides power to the spark plugs so they can fire the air and fuel in the cylinders. If the spark plugs are not getting the power that they need to generate a spark, your BMW’s engine will misfire and stall frequently, especially when you are idling.
Grinding Noises
Another noticeable sign that the alternator is malfunctioning is grinding noises coming from your BMW’s engine. This is an indication that the alternator needs to be replaced because the internal mechanisms have worn out. As an aside, a loose alternator belt will squeal.
Burning Electricity
You may also smell hot electricity while driving your BMW if the alternator is dying. Sometimes, when the alternator loses its ability to produce power, it overworks itself and produces too much power. This overheats the electrical system and causes burning odors.
Warning Light
Finally, you may end up with a warning light on your BMW’s dashboard if the alternator is going bad. A malfunctioning alternator can encourage the engine control module to turn on the battery light, the ALT light, or the GEN light, depending on the available light on your dashboard.
