hi,
i have a small electrical problem in my 1995 defender 90.
i noticed the flasher was getting a bit inconsistent and a few days ago
it stopped working altogether.   now the horn has also gone so i need
to do something about it.

the side lights work fine, main lights are fine, and the full beams
work but only via the 'on' notch, not via the flasher.  indicators are
also fine.

i took off the steering wheel and the steering nacell and took a look
at all the connections.  i pulled out a few of them and checked for
dust and grit but they all seemed fine.  the metal contacts for the
flasher mechanism also seem to be touching fine, i cleaned them off
anyway.   one thing i noticed was that a very tiny spark (like really
tiny) appears between the metal contacts at the full beam 'on' notch,
when the main lights are on and when i put on full beams.  if the main
lights are off (or just side-lights) then there is no spark when i put
on full beams, but then the full beams don't work anyway unless the
main lights are fully on.
does that make sense?  hope i have explained it ok.  at first i thought
it would need a new switch but since all the lights actually work, i
don't want to go out and get one if it's something else.

any suggestions are greatly appreciated
thanks
