There should be a little egg shaped alloy cam on the top of steering column immediately behind the steering wheel hub.
It is this cam contacting the ears on the indicator switch which causes the indicators to cancel.
Not sure if the cam came fitted to the upper steering column when Morgan sourced it or whether it was done in the factory. Its pretty crude so probably it is a factory part.
Now this cam is drilled and tapped to take a small grub screw - probably something like No8 or No10 UNC.
What happens us that the screw slackens or drops out, and the cam remains stationary whilst the steering column turns which means the signals aren't cancelled!
Kind regards
Arwyn
