without an alternator all ur eletrical's will be dead , the battery is just to get the engine started , once the engine is started , all the eletricals stuff depend on the alternator , thats why when ur a/c compressor kicks in , ur lights will be dimmer and then it gets back to normal , cause the a/c compressor shares the same pully with the alternator , when the a/c robs the power the alternator will slow down and then regain speed . basically bigger alternator is much better in terms of supplying the power .

xtorm ,
he was talking bigger alternator interms of amps not size

but basically, how is the alternator able to provide more amp if the size is still the same? i actually agree with xtorm coz my place got one fella where by his car is purposely made for audio show... his car got 8 woofer, 6 amps and to columns of bass mid speakers at only the BOOT of the car... so he needs bigger supply.. thats y then he add another 2 big battery and another alternator to the engine..

means now he got 2 alternators... i asked him wat's the side effect, he said the car feels heavy like u on air cond...

so i think if getting a bigger amp alternator will sumhow produce the similar effect...

I just changed my alternator from 75A to 90A.. no different in term of physical size.. how they produce bigger Amp i dunno, maybe extra 'gelung' of wire inside??

ayell.. in conjunction with changing your alternator did you have to change anything else? :)

 

[ayell]

blur_civic: no.. nothing else.. just take out old alt. the put in new one.. done.. :D

upgrading an alternator is only a choice when u installed power (electrical) hungry gadgets such as a few units of power amp.. it will not increase engine power.. at least not noticable if there is..

upgrading alternator while expecting increase engine performance would be a waste of hard earn kepala agung..

[/b][/quote] bro , like ayell said , he change his 75amp to 90amp and the size is the same , and i`ve seen the size of a 125amp from a corvette and a 75amp its just the same . no point wasting time on using dual alternators la , where else you can only use one which has a bigger amp output which is able to support the audio system . i can bet with you that the , person who told you he was runing on 2 alternator won't come close to a aircond drag feel . compressor is to compress , your engine needs to put more effort by turning the pulley to get the freon gas compress , where else alternators is surrounded by magnets and its able to spin freely to charge and to supply eletric . you wanna see the difference between charge & compress ?. best example i can give is , get a crank tool and try to crank the crank pulley using your hand , i bet you can crank it with some effort , and now try puting your key into the ignition and leave it in to on position and make sure ur a/c button is engage, this is to make sure ur a/c compressor has been engage , now try to crank the crank pulley again , i bet this time u have to take much more effort to get it crank cause the compressor has been engage . which means ur doing 2 kind of compression 1. engine compression & 2. a/c compression . now you see the difference don't you ?. alternator is to charge and it does not compress , hope u get what im trying to say .

hmm.. i was just trying to tell you all what he told me.. sorry
