since we are on the topic . My car's problem is a little different and i often wondered if uneven alternator brushes could be the culprit. My lights pulse. every light in the car. even my lil CEL light. the car can be idling with everything off. and you can still see the lil CEL light pulsing. what is it? alternator? first thought was voltage regualtor but i checked at the battery and it was reading 14.2V constant. any suggestions? battery??? its like less than a year old. its really annoying..

i kind of look like im pulling people over..LOL
