The TR3A adjustable steering wheel and horn problem

[John Bittner <jbit@erols.com>]

My '61 TR3A is giving me fits.  I would like to collapse my steering
wheel in closer to that dash.  I can move the wheel from the full
extended position about half the distance of the available travel.  If I
continue to push the wheel in beyond that point the horn begins to blow
and I can't figure out why.  Any suggestions?  Thanks in advance.
Incidentally, if I wanted to take advantage of the wonderfulness of
Scott Harper of Team Triumph, how would I find him?
