... the near side headlamp and ABS electrical circuits?
Answer: Earth point E101 ~ which promptly came away from the inner wing when I put a spanner on it - d'oh!
30 minutes of improvisation later and hey presto! both the headlamps are nice and bright and the ABS warning light doesn't come on when I turn the headlights on. Job done! Time for a beer (or two) :D
