A failing alternator can cause multiple electrical issues. Common warning signs include:

Dimming o r Flickering Headlights – Especially noticeable at night o r when using multiple electrical components.
Battery Warning Light on Dashboard – Often the first indicator of an alternator problem.
Weak o r Dead Battery – If the battery keeps dying, the alternator may not be charging it properly.
Electrical Issues – Malfunctions in power windows, radio, o r dashboard lights.
Engine Stalling – A weak alternator can cause the engine to shut down due to insufficient power.
Burning Smell o r Strange Noises – A failing alternator may produce a burning rubber smell o r whining/grinding noises.

If you notice these signs, get your alternator tested immediately.
