Maybe I Won't Have A Horn?

    I have been having trouble installing my steering wheel I got from Walcks. There are 1/2 inch of threads on the splined shaft for the steering wheel. My steering wheel just seems to come to a stop when I put it on the splined shaft. When I install the nut and tighten it down it does not go further down the splines and there are just enough threads for the nut to be fully engaged on the threads, no threads above the nut. When the horn button and brass concave plate are installed they are too far away from the contact and when pushed to honk the horn the brass concave plate just pops and becomes convex and does not make contact with horn button.

    I threw in a picture of my steering wheel puller in action. It is a single post hydraulic bumper jack at least 50 years old. I remember using it at my dad's Shell Station in 1965. You just have to put some pressure on the wheel, not to much, and hit it a couple of times with a rubber mallet. This jack has saved my butt many times.

    Law says you gotta have a horn. Mine is a spring-loaded push-button that is clamped to the side of my steering column. The JEEP came to me without either horn button or horns. Or a center view mirror, either. All required by law.

    I would give Walck's a call if you have not already. They are quite knowledgeable about such things.

    I just took mine apart for you... For comparison.

    My horn wire isn't hooked up due to the PO modifying the column, but the guts were still there. Maybe get a longer spring? Or extend the plastic collar to force the horn wire closer to the button?

    For those concerned, I have a dash mounted horn button.

    Thanks, I have called Walcks 3 times and sent him pictures. I have worked on it today and have the steering wheel sitting lower on the shaft. I'm positive I'll get it worked out, some things just take a little longer than others. Your setup looks pretty much like mine, so I'm close.

    Been thinking about the horn issue and understand it better. The horn toots when the ground is made thru the shaft and wire button. How that actually works is the brass cup is an electrical conductor extension of the shaft so when the wire button and the brass cup make contact thru the brass disk the horn toots. So I think the idea is to have the button touching the brass dish all the time and when the brass disk is pressed the disk touches the cup and bingo the horn toots.
    Ya'll probably knew that already, but I'm a slow learner. Now I just have to shim the button, brass disk and/or brass cup to make the above happen and then BINGO.
    As far as I have looked I have never found a good explanation of this in the literature.
    BINGO.

    Correct.

    The underside of my horn button (rubber) has a wear mark from the top of the ground wire.

    I'm curious about something.

    Have you jumped the grounding wire to the steering column's 2" brass ring to ensure the horn circuit works?

    Yea, horn don't blow. NO BINGO. No current coming out of horn in black ground wire and there should be, Need to get horn working then work on button.
    Getting there. Not sure if horn can be fixed or need a new one. Haven't messed with it the last 2 days, but will tomorrow.

    I haven't put a volt meter on it, but I have put a test light on it and shows current going in horn thru red wire, but nothing coming out of the black wire and I believe there should be??? The voltage should be all the way to the horn button wire at the horn button. When the ground is made by pushing on the horn button the current should flow and horn should toot. BINGO. Is what I have said above true?????

    The best thing to start with is:
    - Supply direct power to the positive horn terminal (red wire location) from the positive battery post.
    - Connect a wire to the horn's neg term (black wire's location). Take the free end and make contact on a good known grounding bolt or the neg post on the battery.

    If the horn sounds, you can confirm a operational horn (you might have to to blow the horn out with air to clean it). If the horn fails, you have a bad horn.

    Based on a working horn and direct battery power:
    Take the black wire from the horn and touch it to the brass ring at the top of the column. Now bridge the horn wire from the center of the column to the brass ring. If it works, you can confirm that part of the horn's circuit is working. If it fails, find and repair the issue. Once that part of the horn's circuit is operational, move to ensuring that the stock power source supplied to the horn is working.

    Make sense?

    Once everything is in order, test the steering wheel's horn function as it's intended. If it fails, the issue is solely at the rubber horn button/disc itself.

    Bummer, but at least you can rule it out.

    You can continue to check the horn system using the test light as the "horn".

    Yea, I'll do that. Also got other stuff to do: PTO install, new transfer case brake and parts, but waiting for parts.
    I have a couple ' What to heck is this' posts but don't see how to start a post under that heading???
