I had the impression that my lights and everything won't dim after I bought a cap. Thats not the case.

at idle in my civ. i turn up the stereo and immediately i'm down to 12 something volts. AND my lights still dim. wtf is goin on? I just bought a digital 1 farad cap and it looks as if it works.

it has a automatic digital display that lights up when you turn on your car (or if you do anything power related).... and it constantly reads the voltage...

can someone explain this to me? is this NORMAL?
