I’m trying to adjust my horn, it has stopped blowing.
In the past, a simple turning of the screw in the rear , would bring it back.
Not this time,
Please note the horn manufacturer, in the photos.

Re: Horn adjustment
Back it off and lube it with a light lubricant like 3 in one. See if you can get the armature to spin freely without engaging the diaphragm then turn the screw in until it blows.

Re: Horn adjustment
Would do good to clean the contacts while you have the cover off to oil the shaft.

Re: Horn adjustment
It's funny how we get stuck with things. Bulb horns actually were blown by the air sqeezed out by compressing the air in the bulb. Later horns don't "blow "at all.
Motor driven horns make their racket by driving a notched stem against a similarly notched boss on a diaphragm, that racket being amplified by the horn bell.
If the motor works it is a matter of adjusting the load on the two mechanical parts until they produce the desired noise.
