Alternator failure in a Toyota Camry can present several noticeable signs. Some of the common symptoms include:

Dimming o r Flickering Headlights: One of the first indicators is dim o r flickering headlights, especially when idling o r at lower engine speeds, as the alternator may not be providing a steady power supply.

Battery Warning Light on the Dashboard: If the alternator is failing, the battery warning light will often turn on, signaling that the alternator is not charging the battery properly.

Weak o r Dead Battery Even After Replacing It: A failing alternator may cause the battery to discharge despite being replaced, as it isnt receiving the charge needed from the alternator.

Electrical Malfunctions: You may experience power issues with electrical accessories such as power windows, the radio, o r air conditioning. These can all indicate insufficient electrical power due to alternator failure.

Unusual Noises: A whining o r grinding sound coming from the engine bay can suggest that the alternators bearings are worn out o r there is internal damage.

Burning Smell: If the alternator is overheating, it can produce a burning smell. This is often due to damaged alternator components, like the voltage regulator o r diodes.
