My SEnna used to do that, including a very embarrassing lap at the Nurburgring riders club where we were all meant to keepo lights on when at front or rear and the instructors used to go psycho if you didn't have light on. Sitaution got so bad I had to turn lights off at Bergwerk ('bout half way round) and even when I applied brake light it would splutter. (you ever tried to go round 'ring withOUT braking?) In the end it was a loose connection between alternator and regulator somewhere, so it's always worth checking all connections I reckon. |
