At the moment the silver shim is fitted but it has the earth cable not connected to anything as there is only one connection tab on the horn button. The second tab which is on some (older ?) horns has been made obsolete by the small brass/copper wire that sticks out of the side of the horn this making the earth connection through the steering wheel.

The white connector the live, is then connected straight to the tab on the horn button.

Even if I just put a wire connection from somewhere else around the boss to the protruding wire on the side of the horn I do not get the horn (ooh err....). If I make a hasty connection from the ignition (to act as earth) to that same wire the horn works.

I will try and take a couple of pictures tomorrow.

Try and rotated the silver section within the fittings so that you get a better contact with the thread of the bolts that clamp the steering wheel on. It may be that your not earthing correctly because the earthing ring isnt contacting anything.

Well I washed the car and went to put her back in the garage and decided to replace all the steering column surrounds. Low and behold bizarrely enough after pressing the horn button it worked. I can only assume that the screws completed the earth in the circuit. No shims were wiggled in the making of this horn sound.

Well happy as Larry.

Special thank to Pye21. Thumb

Pip Very Happy
