That's the main reason to use the actual test gear, stops you from getting led astray & it wouldn't be the first time a warning lamp has told lies (for example, 1.9TD oil level warnings/early Xantia water-in-fuel warnings to name just two common ones).
Really you need to check if it is charging first off, and assuming not, check for any output at the alternator itself as mentioned above as well as any signal voltages it needs. Then you can work from the results you get, it may just be a blown fuse preventing the alternator from "seeing" that the ignition is on but the multimeter should be your first priority to fix/replace
No, my multimeter is not working yet and I couldn't find its problem but I borrowed another device to check voltage and the result was negative (no charging). My alternator didn't charge the battery and the voltage was 12V which means the car was running on the battery alone without being charged. So, my warning light is real and alternator is not doing its job. Now, I want to know which part inside the alternator is causing the problem. Voltage regulator or other parts?
By the way, this is my multimeter. As you can see in the following video, it just blinks without showing any voltage!
I'm really unlucky because my alternator and multimeter both went wrong at the same time!
