Weak air horn

Recommended Posts

Hi,

 

I need the horn fixed for the MOT. It is a FIAMM brand air horn, with a compressor feeding the horn by a hose.

The terminals to the compressor look clean. and I can hear the a buzzing sound when activated. Occasionally, a verry weak screachy sound comes out of the horn, but I expect it to be louder and more consistent to call it healthy.:lol:
I have disassembled to some extent. Detached the two plastic lids on the top and the bottom of the plastic horn, found nothing more than regular dust, the core looked clean.
 

Then, on the compressor side, I took the top lid off (three bolts), the sight was not a pleasant one, some residue from a sponge like material on the intake side, a dead spider, a small block of porous material and a loosely positioned spring on top of that block (don't  know if this is by design).

Anyone with similar issues and any clue about how a normal horn should look like on the inside?


Best regards,
Kagor

Is this the original black twin horn unit?

I never had much success with those.

 

I’d replace with a twin air horn set. The trumpets down in the same place.

Hi,

 

it looks like this one here (borrowed image), 
PEUGEOT 205 GTI 1.9 Fiamm Air Horn (Spares) - £11.50 | PicClick UK

Seems like the trumpet body has two canals, two mirrored parts fused together. Cost effective -_-
About the hose, there is a "tee pipe" and the hose is connected to only one of the two connections. I guess one is inlet and the other is outlet for the air.

I cleaned out as much as I could, will see if it sounds better now. Otherwise I'll have to replace it with an electric horn I have at hand, not as cool.

But the question still remains :D If anyone has restored one of these properly, let me know.
 

 

Best regards,
Kagor

You get a large compressor in a twin horn set it’s normally a fiamm too.

You could get one to replace. I think I’ve got one here but it hasn’t been used for 15 or so years!

I’ve had both bits fail. Try the horn itself using compressed air to see what you get. The compressor is easy to get another, the horn is not.
