my baleno is also draining battery in about 2 weeks. I showed it to the electrician. When the car was switched off, battery showed 12v then he pushed a button on his meter for load and voltage dropped to about 10 volts. Then I started the car and switched ON lights,AC and radio battery was showing 13 volts at that time.
Now from this he concluded that battery is fine and generator is weak so he adviced to change the alternator.
So is he right? should I change the battery or generator?
