My horn has not been sounding too good lately so I took it off to check it out. I took it apart and everything looked good so put it back together. I tested it directly to the battery and it sounded great. But when I hooked it up to the wires and pushed the horn button it didn't sound so good. Like it wasn't getting enough juice. Do you think my problem is where the horn rod makes contact in the light switch at the bottom of the steering column.

I would say that is a very good possibility as there could be oil, dirt, or plain crud there that is interrupting the flow of pixies from the horn to ground. It is also possible that the horn button itself has dirt in it.
Are there any problems with the lights? If you also have a bit of a problem with the lights, it could mean the goop from the steering box has crawled down and is slowing the pixies down.
Might be time to remove the light switch off the bottom of the column and lightly clean it.
Be damned sure to disconnect the battery before starting this!!You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command! -
Yes, could be the horn rod connection; however, often overlooked is that lots of times one can "quickly" tune up a "sick" sounding slow rotating Model A horn by occasionally:
1. Taking a tooth pick to clean out the horn bushing(s) black ...... "oil-mixed-with-worn-brush-residue" ..... that has collected in between the multiple transverse separations on the commutator; and,
2. Next, place a Q-Tip on the commutator, and rotate the commutator followed by immediately discarding "dirty" Q-Tips; and,
3. Continue cleaning the rotating commutator until Q-Tips are white and are no longer appearing to clean the commutator. The (2) contacting soft horn commutator brushes will get cleaned by rubbing a "cleaned" metal commutator with recessed transverse separations..
4. If very dirty, and horn was very "sick", one may want to try repeating steps 1. through 3 prior to dismantling everything..Comment

try putting a drop of ATF on the rear of the armature shaft, spin it with the cover off then another drop
put the cover on and readjust

When I took it apart all looked good. There was oil on the shaft end and everything looked clean. The motor spins easy by hand. I will try cleaning up the light switch aria. The lights do work fine but I know there is some oil in there.Comment

The horn must have a good ground. Original ground for the horn grounds with the headlight bar when the horn bolts to it. You can run a wire from the horn motor frame under the horn cover through the conduit then attach to the frame of the car. They also make a horn relay that goes under the horn cover so the horn motor current doesn't go through the horn button, just relay coil current. I have both of these and horn never fails to make correct sound.Comment

Fordman: The (stock-wired) horn has a dedicated hot wire and the ground is provided through the horn switch on the other lead. At least mine is that way. I don't think the horn uses the headlight bar ground unless you are using a horn relay.Comment

When you install the horn cover are you using a original screw? Most of the reproductions will tighten to far and you have to back it out for the horn to sound good . The original screws only have threads part way to the head so it can only be tightened so far . NormComment

I have an original Sparton that's in great shape on Pops, my '29 Tudor. The horn has been intermittent. When I press the horn button most of the time I don't get any sound, but I do get a spark coming out of the horn button. I had the wire connections at the base of the steering column apart last week and couldn't see anything wrong with it. I'm not sure what to do about the 1) sparking, and, 2) The...02-08-2021, 12:02 PM -

I need help with a horn issue, not on Jesse’s car, but on a buddies. His horn worked until his starter was replaced. Now horn will not work. There is constant power at the horn & it has an aftermarket headlight & horn assembly on the steering wheel. Anybody have an idea??03-20-2020, 05:52 PM -
My Tudor's horn is inoperative. The ammeter drops when I push the horn button though.
Any suggestions appreciated....04-08-2023, 10:47 AM -
OK, not a show stopper question but just a minor annoyance. I suspect a poor ground, probably too much paint in places where it should not be because all the wiring was replaced and the horn blows fine when it gets enough juice. Will a horn relay fix this? Yeah, I know it's a band aid approach.........02-19-2018, 11:07 AM -
I drive my roadster during the winter in FL. It is always in a workshop with two dehumidifiers running so I am not getting any rust or mildew. I noticed last winter that the horn was sounding a little sick, but did no investigation. Now I find that when I push the horn button it starts to sound a little like the horn but pretty weak, and only for about 2 seconds. If you hold the button on, it just...You do not have permission to view this gallery.

I'm hoping y'all can help me think through a grounding problem. Here are the symptoms:- When horn button is pressed, horn motor turns, but more slowly than normal
- Changing the angle of pressure on the horn button changes the speed of the motor
- Pressing the button at all causes the headlights to turn off; releasing it turns them back on
- Connecting the horn motor directly to the battery causes

I have been making great progress getting the 30CCPU back together. Finished wiring and testing the blinkers and headlights. Everything was working great, so I trimmed and wrapped the wiring. I gave myself 5 stars for the job.
As I was cleaning up, I remembered the horn. I figured I would give it a test. Nothing. Checked the wiring diagram, and I have power on both wires going to the...06-02-2021, 10:01 PM -
Somebody called himself a knucklehead. Well. here is another one. I have had problems with the horn on my 31 Tudor and have been taking the back cover of multiple times. The last time I guess I didn't tighten the screw enough since it come off while I was out driving. Yes, you guessed it, the cover came off and the car behind my ran it over making it into a flat piece of metal. So, here we go....05-31-2018, 08:31 PM -
