Mike:
The bearings within the column are moulded in the rubber and insulate the
steering shaft down through the column housing(cowl), and many times the
rack will be insulated from the frame because of the Rack mounting rubbers.
Even though the steering rack may have a ground wire attached from the
harness you may have lost the ground through to the Chassis which I believe
for the forward harness attaches just below and behind the grill. A simple
test would be to place jumper leads to the steering rack and ground on the
Battery.

Subject: Horn problem - hoping to end my saga
Sorry to continue to labor on this horn issue with everyone. I have truly
valued the input I have received to date.
In checking my horn connection, I have continuity from the horn all the way
to the wire brush. However at this point something doesn't seem right.
If I connect a wire to the end of the horn brush and touch the other end of
the wire to the threaded steering column, nothing happens. However if I
touch the end of the wire to the edge of the steering column cowl the horn
beeps.
In taking everyone's input, reviewing the available diagrams in all my TR
catalogs (plus Dan Masters book) and following the mechanics of how the horn
seems to function, the conclusion I drew is that the connecting link that
beeps the horn goes something like this. The horn button pushes the brush
against the slip ring and at the same time grounds against the side the
steering wheel which is bolted onto the steering column which is grounded
down near the steering rack on the left side of the car, and bingo, you have
a connection.
However, if I lean in real hard on the bottom side of the steering wheel
(which brings the steering wheel in contact with the steering column cowl)
the horn will beep. Is this a symptom of the bearing assembly (or some
other insulator) in the steering column that is not functioning properly?
I would appreciate any input to help me fill in the blanks and solve this
problem.
Mike
