Additionally, you may notice unusual noises, such as grinding or whining, coming from the engine compartment.

How can i tell if alternator is not working on a 2002 ford focus?
Usually the appropriate warning light on the dash will come on if the alternator is not producing current. If you don't trust the warning light, take a volt/ohm meter and (making sure it is set on the DC reading scale) connect it across the output terminals of the alternator to determine if any current is being produced.

You may suspect your alternator isn't working if your vehicle experiences dimming or flickering lights, frequent battery issues, or a warning light on the dashboard that indicates a charging system problem. Additionally, if the engine struggles to start or stalls unexpectedly, it could indicate that the alternator isn't charging the battery properly. Testing the voltage output with a multimeter can confirm if the alternator is functioning correctly, with a healthy reading typically around 13.8 to 14.4 volts while the engine is running.
