- Load test: Turn on the headlights, radio, and other electrical accessories while the engine is running. If the voltage drops significantly, the alternator may not be providing enough power to the electrical system.
- Visual inspection: Examine the alternator for any signs of damage, such as cracks, leaks, or loose connections. If the alternator appears to be in poor condition, it may need to be replaced.
If the tests confirm that the alternator in your Chevy Cruze is faulty, it's important to have it replaced as soon as possible to avoid further damage to your vehicle's electrical system.

How does a vehicle act when the alternator is going out?
When an alternator is failing, a car will often show signs of electrical problems like dim or flickering lights, malfunctioning accessories, and dashboard warning lights such as the battery or check engine light. It may also make unusual noises like squealing or grinding and can lead to difficulty starting, frequent stalling, or eventually shutting off completely as the battery drains.
Electrical symptoms
- Dim or flickering lights: Headlights, interior lights, and dashboard lights may dim or flicker, especially when other electrical components are in use.
- Malfunctioning accessories: Power windows may move slower than usual, or the radio and other electronic devices may act erratically or stop working.
- Warning lights: A red battery, check engine, or "alt" warning light will likely illuminate on the dashboard.
- Dead battery: The car may struggle to start or fail to start at all, and a jump start may only keep it running temporarily before it dies again.
Auditory and other symptoms
- Unusual noises: A whining, squealing, or grinding noise coming from the engine area can indicate worn-out bearings or a loose belt on the alternator.
- Burning smell: An overheating alternator can produce a burning smell.
- Stalling: The engine can stall while driving if the alternator fails to power the ignition system, leaving the car without power.
What to do
- If you experience these symptoms, it's best to minimize electrical load (like the radio and air conditioning) and get the car to a mechanic as soon as possible.
- If the car dies, a jump start will only provide temporary power, and it is unsafe to continue driving, as the car will likely stall again.
