Horn Boss setup with Moto lita steering wheel

Stuart - thanks for the advice, I will take a look. Just a thought - is anything else earthed through the column that would give me an indication whether this is the problem?

Thanks as always

No, just the horn.

Thanks for confirming Jerry

Following Stuart's earlier suggestion I decided to check continuity to earth at intervals down the column from the top splines down, across the doughnut and the u/j to the chassis. And also from key points in between straight to the chassis. Every test (down the column or straight to earth) confirmed continuity. As a novice at this sort of thing, this suggests that the earthing of the horn is not the cause of the original problem and implies there isn't a problem with the earth link wires across the doughnut and u/j (despite the link across the u/j looking a bit ragged!). 

I am scratching my head a bit now (and possibly questioning myself too much) so it would be helpful to get a second opinion on my view that the earth is OK despite the horn only working when I earth it directly from the 'push' rather than through the column.

Thanks

Dave
