The alternator in your Toyota Camry is responsible for recharging the battery while the engine is running. If the alternator is faulty, it won’t be able to charge the battery, which means the battery will gradually lose its charge and eventually die. Common signs of a bad alternator include dim o r flickering headlights, a burning smell from the engine bay indicating potential overheating, and the battery warning light staying illuminated on the dashboard. You may also experience electrical failures, such as issues with the radio, A/C, o r power windows. To confirm whether the alternator is the issue, a mechanic can test the alternator’s voltage output. The voltage should be between 13.5V and 14.5V if it’s lower than that, the alternator may need to be repaired o r replaced.
