My Motohorn died on me this weekend

[CloverHillCrawler]

Well it happened again. I had to fix my Motohorn a little while back and make myself a diaphragm after the compressor blew the original one out, but I was out this weekend and it died right in the middle of giving a toot to some kids who were waving as I was going by. It just died mid way through the blast and never came back.

I pulled everything off today and no loose connections and getting 12v from the relay to the compressor but it's not running, you just hear the click of the relay and I can feel the compressor trying to do something but it seems to be jammed.

Unlike the last time, Motohorn is selling spare parts like compressors now, but they are out of stock. So for now, the little BRP beep beep horn is hooked back up.

May be it's time to start looking at another horn manufacturer.

I bought a package of 2 Wolo Bad boy Air Horns on Amazon for $50 dollars a few yrs back. They make a good noise and they're still going strong. I see they now cost more than that for 1. Auto part stores carry them too, I've seen. Just a thought.

Thanks, but I contacted Motohorn support and they stated they will have some replacement compressors in about 2 weeks and they are $39. So I guess I gotta live with my mouseketeer BRP horn for now. Luckily enough, I left the stock horn on and just had to swap the leads from the relay back to the stock horn. I left everything else in place in case I could find the compressor. So when I get it, it will be a quick swap out.

Over the years, I've found with quite a few of these compressor type horns that you need to be a little careful with where you place/mount the compressor and orient it so that its air inlet and the body drain aren't exposed to any road spray, rain/washing water, or dust/mud/bug entry; and the same goes for the horn trumpets themselves!

If you don't pay attention to how they're all angled and any road spray from the wheels &/or underbody when riding while it's raining or even if you're just riding thru puddles can get blasted into any of those open holes; if any rain or washing water/spray can get under the bodywork and then run or drip into those openings; or if too much in the way of dust/mud/bugs can get blown/sucked/blasted into any openings, then these 'compressed air' type horns tend not to work for too long!!

The tiny little holes on the sides of the compressors that I've used have been particularly problematic, it's often really hard to fit the compressors in such a way that they don't get a blast of water/dust/mud from somewhere (I've even resorted to making shields/covers for the compressors); and if your horn system has those trumpet thingies, their 'sound output' nozzles really need to be angled down and backwards, or at least protected from any dust/mud/bug entry or they too will clog up fairly quickly!! And even when mounted in the ideal position, you should occasionally give them a bit of a clean out/back flush - you might be surprised at how quickly they'll die if anything goes in the wrong way!! Or given the subject of this thread, maybe you won't be?!

You know the old saying, once bitten, twice shy!! I would find a different toy to putt under the hood!
