Hello.
All the car lights have started to flicker all of a sudden. Also the car multimedia restarts when i turn on the lights of the car.
Is it the alternator or something else. How to quickly diagnose
Please do mention some details regarding your car; make, model, model year, etc.
Most common causes can be problems with Alternator, loose or disconnected ground wires or ignition wires, after market equipment, battery, voltage regulator, etc. Check one by one, and take remedial action accordingly.

Thank you.
Car is 2011 civic. Nothing aftermarket installed totally stock. After an hour of parking it. The car is just fine nowm i guess i have to clean them terminals on a sunny day.
Yup check terminals and ground. Most flickering is caused by disturbance caused by improper ground or rusted ground etc.
