Default Headlights flickering

On my girl's 02 TA her headlights will go from bright to dim about 1-2 times a second, but only when her engine is running. The interior lights do the same thing, but it is not as noticable. What is going on, and is it a major problem?

mine only do that under start up sometimes... i think it has to do with the alternator not being warmed up.

This happens anytime the engine is running, so its gotta be the alternator/power regulator.

From what they reported at ls2.com it is from the air system circulating and not enough current going through the wires. People who change the battery wires and or !air dont report this problem anymore.

If this is correct every one can verify this by removing the fuse to the AIR pump. Anyone want to give it a try and see if it works?

If you have an aftermarket stereo, it would be your amplifier drawing too much current, and that is where a acr audio lightning capacitor would help you, or you may need a bigger alternator cranking more amps.
