Don’t see or can’t find a definitive article on how to rebuild these low note high note horns.
Adjustment screw makes no difference, good ground, 12v.
Any shop or member rebuild these?
I've taken a few apart to repair, with mixed results - mostly bad.
First check that you still have continuity with a voltmeter, across the two leads and that the power leads are not shorted to the horn body. If open across the leads or has continuity against the horn body, the horn is done.
Next drill out the rivets and separate the halves to get at the points. Clean and burnish the points as much as possible and reassemble using small nuts and bolts and then try it again. That's about all you can do with them. Good luck.
I have rebuilt them, and every horn worked great. They get very dirty and rusty, the diaphragm mostly.

Triumph also used clear hooterI have a couple of Clear Hooters that came with a bunch of parts, but can't be sure they are from and Alpine. One is marked H on the bell and the other is marked HH. I can't say I have heard an original Alpine horn before, but the two of these together is pretty high pitched. What did they actually come with?
I was sort of expecting one to be H (high) and one to be L (low). HH = higher than high? What are the markings on original Alpine horns?
My SV are marked H&LI was sort of expecting one to be H (high) and one to be L (low). HH = higher than high? What are the markings on original Alpine horns?
