Yep, this happens when the contact plate is grounded or the horn pad is worn out. Make sure the horn pad contact lines up with the receiving end of the contact plate.
Check out the images (below). Please let us know what happens.

I check in all data there is nothing, the horn blows when the circuit is grounded. Can you remove the green bit so I can see under it? Please upload an image.
