TR6 TR6 horn button

[Tinster]

Jeff,

Thanks but I'm still confused. The inside of my steering
wheel head is an empty, hollow space with nothing there
at all. That piece 115 must go somewhere, since it is shown.

BLARGH!!!! I wish there was a Six around I could go look
at. It would instantly click in, I'm sure.

Dale, #115 goes inside the <u>column</u> itself.(The skinny tube.) The outside diameter goes against the inside of the <u>column</u>, and the steering shaft goes inside the bushing. The horn contact ring fits inside the cup shaped bowl on the end of the skinny bit.
Look at the illustration again. You'll see another #115 at the other end of the column. These two bushings support the shaft inside the column.

Dale, the horn push connects the disc with the wire to ground via the springey bit to the steering column. The wire from the disc connects to the wire you are touching to the shifter.

Dale, the rubber thing in your photo is a steering column bushing, unrelated to the horn in any way. #115 here.

as Paul stated weeks ago at the start of this horn episode

My new horn button and DPO Pedro's
old broken horn button both have two wire spades. What
wires connect to the two horn button spades? d

Those spades are not for our car. Probably for a different car.

Don,


The spring brush I can almost visualize as a contact of
some sort for the plastic disk. How it relates to the two
spades on the horn button, escapes me.

That goes into the hole @ the twelve oclock position on the wheel.

Don,

My horn button inserts and snaps directly into my steering
wheel center. The three prong thing is not needed, as far
as I can tell.d

That prong clip is what the cap actually sits on and is needed. When you push the center the horn buch connects to the piece under the wheel and grounds out the horn.

Somebody jump in and help!!

Somebody jump in and help!!

Don-

At this point I realize I can help by keeping my mouth/keyboard closed. I am done on this one.

I wonder why the Big Three are selling these two spade,
TR6 horn buttons with Triumph shields on them.... if they
are not for Triumph TR6 cars?

Curious to say the least. I now own two.

Don, could you take a photo of the back side of your
horn button?

Dale, is there a Lucas part number on this (truly bizarre) horn button? I don't think I've ever seen such a button for a Triumph with those tabs, so I'm really puzzled! /bcforum/images/%%GRAEMLIN_URL%%/confused.gif

Dale,

Here is the rear of my hornpush:

The end of the rod (to the left) is positioned so that it touches the metal tab you can see on the back of the hornpush. The metal spring/wire you can see at 1 o'clock on the edge of the hornpush touches the steering column when the hornpush is fitted, and thus earth. The other end of the rod, inside the steering column, bears against a metal ring, i.e. is always in contact with the metal ring, which is itself connected by a wire to the horn, the other side of which is connected to battery +.

So, when the hornpush is pushed, it connects the horn across battery + and earth.

At least, that is my understanding of how it works.

If your horn push has two tabs on the back, then it can't work the same way. The Grant GT wheel I had on my MGB I remember had two tabs: one for an earth and one for the the horn side.

PS I will be in Puerto Rico for a couple of days at the end of April. Will you be around?

 

[DNK]

That's what mine looks like Dale. Maybe the new ones are some all encompassing!

 

[poolboy]

Yes I think you have it right, Julian. The completion of the ground occurs when the horn button is depressed and the retaining clip (spring) makes contact with the spade. You can't see that point of contact, though, because it is internal to the horn button. ....Wait , where's that hammer!

 

[Tinster]

Julian:

Here is my horn button - I have 2 identical ones.
I took one apart to see inside. When I push the button,
a metal strip inside completes the circuit between the
two spades.

Yes, I will be around all of April, as far as I know.
A vist would be fun.

When you push the horn button, does the spring clip on the edge become connected to either spade?

 

[DrEntropy]

Nope: It's a self-contained switch. All the spring does is hold the switch in place.

EDIT: Julian, your horn push is what all the Triumphs I've been familiar with have had, same as what I've posted in the OTHER thread about this.

I'm coming to the conclusion that the wheel Dale has is some aftermarket one, and the two connector horn push is something from an even later car. No way to mate all that together without a MacGyver effort, IMO.

Dale, the downside to having a horn button somewhere other than the center of the steering wheel is obvious. Not good for emergency horn use.

Bill, its more a matter of just knowing where the horn is. Not all horn buttons are located in the center of the steering wheel. Another popular horn location is as a push button on the end of the turn signal stalk.

Knowledge is not what is used in an emergency. I put about 40k miles on my TR7 in the late 80s, and since have put about 20k miles on my E-type, and I know the positions of the horn buttons in those cars, yet in an emergency I, without fail, punch the center of the steering wheel. I then, without fail, cuss the idiot who moved the horn button.

I just MacGyver'd my horn switch to a stalk 'cause of a short in the center ground of the wheel... Still stab at the horn push on the wheel first. Conditioned like Pavlov's pup.

Welcome to th' fray, sbs! What part of PA are you sittin' in?
