Yes dear Fahad, exactly this happened. The electrician found out that the oil leaked from the hydraulic power steering pump broke the generator's circuit and that the generator needs replacement. It costed around 3500 to replace the generator and since then, everything is fine.
But the power steering makes buzz noise, more than one could ignore. I hear the motor running while I turn the steering. Never heard this before. The mechanic said to use some thick PS Oil. I shall check if that works. Any suggestion on this will be very highly appreciated.
And thank you all who replied a lot. This was my first post and I am very happy to see how this brilliant community tries to help. Thumbs up for the forum, thumbs up for Pakwheels.
