  • Horn Sound

    Is there anything that can be done to a horn other then the adjusting screw? Horn does not sound like most even using the adjusting screw from one extreme to the other.

    Hi Cape
    I usually remove the back cover and put a little ATF on the felts where the armature spins. You can also clean the commutator with a fine sandpaper and make sure the separation lines are defined by running a little screw drive along them. Don't over tighten the rear cover screw or that will muffle the noise. The proper rear cover screws have a shoulder that can only tighten so far, but some replacement screws are threaded all the way. Either way don't over tighten

      Also make sure the diaphram isn't rusted. I've had to replace a couple with a new diaphram from A&L.

        I thought it was against the 'rules' to use anything metal to clean those groves ??

        I use spray brake cleaner and an old plastic credit card cut into tri-angles to get sharp edges to clean those segments.

          Is that the odor that is wafting down from up north?

        The diaphram also must be oriented correctly for the right sound, or to function at all. The wavy washer must hit the chisel point square, so the lines of the wavy washer and chisel point are parallel to each other.

          horn problem
          by lpl87
          wanted to adjust my horn & took out the 2 screws in back instead of adjusting the 1 I should have. Haven't been able to get a sound out of it since. Motor spins but no sound

          Ahooga horn in trouble
          by Tudor31
          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....

          Horn Removal
          by copgib
          While working on my Model A today I read in Les Andrews red book to take the only screw out of the back of the horn to disconnect the wires for removal. Well I tried to do this, but that screw just turns and will not come loose so I can pull the back off the horn. Any suggestions or will I have to start in the front and work my way to the back to take it apart? Any suggestions would be apprciated....

          Horn not well
          by WMWS
          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...

          Horn Goes Ahooga When Engine Running Just Oogh When Engine Off
          by Leo
          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.........

          Got my horn!
          by Beauford
          Got a deal on a Spartan and have zero idea where to hit it with the battery. Two screws on the back I assume? One seems to make a adjustment and the other is just a screw. Going to work now but plan on testing in the morning. Seller says works well....

          I'm trying to get my EA horn to work. I've torn it down and cleaned it all up. When I hook it up, it spins, but seems very slow. The armature is arcing, which I assume is not good. Also, the wires get very hot. Obviously, I have a short, somewhere. I guess I need to find a parts horn or an armature, at the least. I coud probably rewind the field coils, doesn't look to be too hard. The armature might...

          Model A horn and traffic
          by carolinamudwalker
          Have any of you heard how a model A horn sounds at 45-50 mph? I have had 2 close calls recently, One when a guy was coming into my lane and I had no place to go, the other in a parking lot with this jerk just backing out without looking and depending on a horn to warn him. Again I had no place to go because car behind me. I want a truckers air horn with a foot switch, any ideas?

          Horn Adjustment Screw Felt and Wire Terminals Position
          by Tom Wesenberg
          Here's a picture of the round felt pad that fits around the adjustment screw. These felt pads are often missing. I was at Menards the other day to buy some felt door weather stripping, and it would work great to cut a round horn felt. It's 5/8" wide by 3/16" thick, and 17 feet long, and only costs $2 for the roll. It's a medium grey color but could be dyed black by using a felt tip marker....
