My horn is broken....

[Chongwong]

...Should I fix it or get a louder endcan?

[Rubin215]

Fix it.

A louder endcan just means failing the mot for two things.

[Chongwong]

That might be an idea, my only attempt so far is spraying contact cleaner on everything.

Does the horn do nothing at all or just a "clicky" sound,

do you feel some movement inside when you touch it while operating on/off ?

There is a small screw on the rearside of the horn, mostly covered with a dab of paint sealant,

this adjusts the membrane, ever tried to turn this in / out ?

[Chongwong]

No idea, I've not had the chance to try without my helmet on and earplugs in, that'll be this morning's investigation.

I should probably go and look for/at he horn itself Also, as yet I've just fiddled with the switch and looked grumpily at it.

Replace with a Stebel air horn.
I got one for £35 from mx5 parts.
