Battery is just a reservoir , Now that flickering indicates peak load (current drawn at the thump of music) being higher then the peak current battery can provide. But when engine is running as the alternator runs at 13.4 volts first it will be loaded and then when it goes to max capacity and voltage drops below 12 battery will be drained. That flickering was illustrative to drive the point that music system does put a load. Your battery and alternator gets this energy from engine which in turn burns fuel. When engine is not running battery provides current but that is actually from engine during previous running cycle so on an average still fuel consumption is higher as battery needs to be charged again in the next run. So in all music system's load results in fuel consumption. @allajunaki : Perfect explanation mate. That resistance to rotation due to magnatic field is the lenz law which every one studies in 12th standard and also this is inline with law of conservation of energy, More work required to turn shaft means more load on engine.

Try to understand what I am saying, the alternator SHOULD NOT and MUST NOT consume ADDITIONAL power because of loading with basic electrical applications. Less than ADDITIONAL doesn't mean ZERO. When OEM designs a car and ARAI (in India) certifies its mileage, it has taken into consideration the basic power required to turn that alternator.

| ![]() A Few years back..I was training a guy from next doorhow to drive. While driving all of a sudden he took the car off road. I asked him what happened dude? He said " You see there is a truck coming in our direction". When I checked the truck was almost half a kilometer away from us. That was the last time, I helped someone to learn how to drive!! |

| ![]() @Prateek Check the Alto of any of your friends. Idle the car with all equipments off. Then switch on the parking lights alone. The rpm will increase audibly. Now switch on the head lights,again there will be a difference. Ditto when the radiator fan starts to run or the blower/AC is switched on. ARAI certification figures may have factored in these loads on the engine. But if all these things are off, the car may return even better mileage. I have obtained 24+ KMPL figures under the most favourable conditions when no electrical appliance was on except the radio. This is not an ARAI certified figure for sure! |

| ![]() Well then the IIT guy must be under the assumption that the engine is the same, choice is on the fuel depending upon the required performance. @ Alternator issue: it depends on the torque available at idling rpm. |

![]() But I would disagree in the benchmark part - do you still feel it is a benchmark on ride quality? Last time when I had a long ride in an Amby's backseat, I got terrible back pain - due to the unevenness of the seat from sides to center. Last edited by clevermax : 19th July 2010 at 17:03. | |

| ![]() Ok, me and my friend are cruising in my safari. And from no where a black Safari ( very good looking one) zooms past us. My friend asks me to chase the speeding SUV down, which I resist. He wonders what was in that Safari that it could attain such speeds while I could not in my car. Later we catch up with the black thing at the toll plaza. My friend has a good look at the exterior of the vehicle. And then it happened. He yelled its a 4X4! His out-of-this-world logic being that because that Safari was a 4X4, the engine was able to transmit power to all 4 wheels at the same time and hence causing the vehicle to attain astronomical amount of speeds. ![]() |
