Hi all, first post. Had my 58 plate jazz for six months. Has anyone noticed that a fan/motor jumps in and out regardless of whether the engine is hot or cold. It? Must be drawing a significant amount of power as the headlights dip for a second until the alternator kicks in with more power. My first thoughts were the radiator fan, this could be the case, but it seems to operate at any time? Any info would be great. Thanks Gary
