How to fix a motorcycle horn without disassembling

If your motorcycle horn (or any similar horn) stops working because the internal contacts have oxidized, you may be able to fix it without bending off the metal collar that holds it together. I made an educated guess at where the internal contacts might be, drilled a small hole, and sprayed contact cleaner inside. After letting it sit for a few days and spraying some more contact cleaner in the hole, my horn started working again.
The video I found most helpful in understanding how the horn works and where I should drill the hole was this one: • How Motorcycle Horns W...

Here's what fixed it without the wait - remove the adjustment screw, fill with electrical contact cleaner, take a pick and gently depress / agitate the contact inside through the screw hole until the internal resistance goes to 0 ohms, readjust screw so it makes sound again and you're done.

I bought a set of horn on ebay and it did not fit, so I watched this clip and did as you instructed. It works great. Thanks so much for sharing this with us.

This is awesome! Fixed a horn of my BMW airhead, would have been $70 to buy new or half of that on ebay. Thanks again!

Thanks!!! I use WD40 with mine and it works!

I think I'll try this on my old honda CB horn!

Great video but instead of drilling a hole remove the adjustment screw and spray cleaner in that hole then replace the screw

you completely missed half of the operation of the horn, #1 - it does not need to be pulled apart to fix, #2 - the screw with nut is the fix, always, my horn on my wedding cars gets a lot of work, and i have fixed it with the adjusting- tuning screw , 6 times, ,,, here is what you missed.... insert ear plugs, loosening the nut under the screw- frees the screw for movement, .. with the 12v power on, you winding the screw out- allowing the top contact to always stay connected the the bottom contact- thus max - un breaking current, - ONE pull of the magnet, and NO SOUND, then you wind "in" the screw until it allow separation of the contacts- horn is sounding, then 1/4 - 1/2 turn more for operation, re-tighten the nut, SO one horn will thus last the life of your bike - cars - truck, wedding car

[@jeffpotter3476]

Hi... PLEASE EXPLAIN AGAIN! I mean, I will try to do the actions you state. But I cannot understand what is happening. Mysterious! What is a pull of the magnet? Unbreaking current? Why is winding "in" in quotes? Help!

Swag. The horn on my 83 suzuki GS550L is seizing up. I have to smack it to get it working so I think I'll try this.

I like your text ring, lol.

Travis Stump did you really need 2:56 to tell this?

Mustafa Cam He went out of his way to share a superb hack, give props where they're due!

horns are disposable.....you can save about $5.00 and tear your old horn apart and spend money on contact cleaner and waste a few hours scrubbing the film off of the horn contacts and outer shell OR just go on e Bay or your local bike shop and pay $15.00 for a cheap horn. I use my horn maybe 5 times a year (if that), so I don't need a fancy horn.

[@darkshadowsx5949]

if you actually care about keeping an old bike original a random new horn is not going to fly.
and you can use the contact cleaner on other things as well as keep that old horn going for years.
