Hi Paul,
the trigger ring should fit into a slot, it's possible that the steering has been
re-aligned at some point and this is placing the trigger "out of phase"
Be careful removing the steering wheel, or you could lose a couple of teeth.
loosen the nut but don't remove it, this will stop the wheel hitting you in
the face. you can then see the trigger, check its position it should be directly
aligned with the centre of the indicator switch, if not remove it, it will have a
spring clip around it but it should pull off quite easily, reposition with a spot
of glue in necessary.
If it is in alignment then it's a switch fault, you can take the switch apart and
check the internal parts are functioning, you can also check its operation by
holding the little lever and operating the switch, then flick the little lever to
see if it cancels.
Sorry a bit long winded and you may already know most of the above.
regards
Geoff
