The alternator is the part in your Mazda’s electrical system that generates voltage. A healthy alternator can generate anywhere from 13 volts to 14.5 volts. Mazcare advises that the alternator generally lasts around 10 years. If you drive an older Mazda and you notice any of the problems listed below, it’s possible that your alternator is going bad and needs to be replaced.
Accessory Problems
Your Mazda’s accessories should work without any problems. Signs that the alternator is going bad include slow power windows and seats, problems with your entertainment system, and problems with your navigation system. You may also find that your USB ports do not charge your electronics.
Battery Light
The above accompanied by the battery light on your dashboard definitely point to the alternator. If you drive an older Mazda, you may end up with an illuminated ALT or GEN light on the dashboard. This is the warning light for your vehicle’s electrical system, i.e., the alternator is having problems.
Burning Electricity
When your Mazda’s alternator starts to go bad, it will try too hard to produce voltage. In some cases, it may end up overloading the electrical system and you will smell hot wires and burning rubber. This can be dangerous because you don’t want the alternator to start an electrical fire.
Dead Battery
If your battery is dead and does not maintain a charge when you jump-start it, it’s probable that your alternator is going bad. The alternator is the electrical system part that keeps the battery charged. As the battery discharges, it generates voltage to recharge it.
Dim Lights
You will also notice a difference in the brightness of your Mazda’s lights. If you are finding it harder to see when driving at night because your headlights are dim or flickering, this is an indication that the alternator is going bad. You will also notice that your interior lights are dim.
Frequent Stalling
Aside from your vehicle’s accessories, the alternator also powers the spark plugs. If it is unable to generate enough voltage for the spark plugs to generate sparks, your engine will misfire and stall frequently. Replacing the alternator usually solves the problem.
Growling Noises
Finally, growling noises coming from your engine could be coming from the alternator if its internal mechanisms are grinding against each other. You might also hear whining noises that indicate a problem with the alternator belt.
