Checking an Alternator on a Chevy Cruze
To check the alternator on a Chevy Cruze, you can follow these steps:
1. Use a Multi-Meter: A simple way to do this in your own driveway is to use a multi-meter. Set the meter to DC voltage in the 12-volt range. Place the positive lead on the positive post of your battery and the negative lead on the negative post. The voltage should be between 13.6 to 15.8 volts when the engine is running at around 1500 RPM. If the reading stays the same or drops, it means the alternator isn’t charging and may need to be replaced.
2. Check Symptoms: Some common symptoms of a bad alternator in a Chevy Cruze include slow cranking of the engine, clicking noise and no start, flickering headlights, whirring from under the hood, a battery warning light on, and accessories like the radio not working reliably.

5. Consult a Mechanic: If you’re experiencing issues with your alternator, it’s best to consult a mechanic for a thorough diagnosis and potential replacement. The cost of an alternator replacement can vary but typically ranges from $375 to $1,100.
