well you can't blame the battery. using the battery alone doesn't cause dimming. try turning your car on and use accessories. i doubt anything will dim. the dimming is caused by power switching from the alt to the battery 14v to 12v thats why it dims. it switches to the battery when there is not enough power output from the alternator.

I dunno ... it's the alternator that came with the engine ... I'm assuming it's just right ...

okay, I'm a retard. let me amend what I said about my lights dimming ...

they ONLY dim when my windows are already up and I'm pressing the window up button. I don't know why I know that ... I guess I just like to mess around ;P

yea that takes tons of power because of how the pw motor is setup. i've had a voltmeter drop 2 full volts when i did that with both windows together.
