okay i took the horn out, I guess its the standard horn as i showed on the previous post. But i don't have that round cover.
I adjusted the nut in the "middle" of the horn as you can see in the picture.The horn still kinda clicks. not the relay (or maybe the relay too) but the click comes from the horn itself.
When i ground the horn, and connect the positive side of the relay, and then ground the relay, it kinda horns, but sparks fly all over the place and the horn started to smoke. So i guess the horn itself shouldn't be grounded? Or should it?
I don't really understand how it works..
