IF YOU CONFIRM:
A low-tone whistling noise comes from the alternator for not more than 10 seconds after the engine is shut off.
ACTION:
Please note that this noise is:
- Normal and is caused by a rotor “slow-down” function that is designed into the alternator
- NOT a failure symptom, so do not replace the alternator for this
