In my case, i noticed slight flickering of meter lights. The flickering was more pronounced when i put vehicle under sufficient electrical load i.e steering turn, headlights on full beam, radio on, full blower, cabin lights on etc. I could see the voltage drop below 12 V on car's mobile charger/ voltmeter, as shown in picture. I would even get an error message of EPS on car's meter, due to low voltage. After getting vehicle inspected from 2-3 good electricians, faulty alternator was identified. I fixed it in around 1500 Rupees.
