My girlfriend has a 97 civic, and the electrical system sort of flickers or sputters from time to time. I would describe it as going from 100% down to 50% momentarily, then back up to 100%. You notice it when the headlights suddenly dim. I really noticed it last night when I was looking at it from the outside and saw the tail lights flicker. It only sputters for less than a second, but it is annoying and i'm sure unsafe. Anyone have any ideas or have seen this before? It almost seems like the whole system has a bad ground or something. The battery does not have any corrosion on the posts. Thanks.
