Thanks for your reply. Just decided to delete post as it seemed to annoy someone!
As ever, went out to Disco yesterday afternoon, did exactly the same as before and it burst into life...which means that by the time it reaches Strathearn (who are great by the way if you're close to Perthshire) they'll have no chance of finding out what it was. Still, the ace light, 3 amigos, rear windscreen wiper, oil leaks, rear passenger window and leaking sunroofs should keep them busy...
Cheers anyway...hoping to be of more use soon, and looking forward to posting.
