What are the signs of a failing alternator in a 2013 Ford Mustang Boss 302?

Dashboard Warning Lights

• One of the most obvious signs is the illumination of the battery warning light on the dashboard. This light may appear intermittently or continuously, indicating a problem with the charging system.

Dim or Flickering Headlights

• When the alternator starts to fail, it struggles to provide consistent electrical power to the car's components. This can cause the headlights to dim or flicker, especially when using other electrical accessories like the radio or air conditioning.

Electrical Issues

• Failing alternators can lead to various electrical problems in your Mustang. This might include malfunctioning power windows, a radio that cuts in and out, or issues with other electronic features in the vehicle.

Strange Noises

• A failing alternator can produce unusual noises such as grinding or whining sounds. These noises typically come from the engine bay and may signal that the bearings within the alternator are wearing out.

Battery Problems

• If the alternator isn't charging the battery properly, you may face issues starting the car. You might find that the battery is dead or draining quickly even after being recently charged.

Burning Smell

• A failing alternator can cause the electrical system to overheat, resulting in a burning rubber smell. This could be due to belts slipping or electrical wiring getting too hot.
