Could BOTH my horns be bad?

Then ran piece of 14GA wire from the + post and touched it at the post and the terminal on each horn, nada.
Removed the horns from the brackets and laid them one at a time over the - battery post and touched the wire from the + post to the horn terminal and nada.

Effectively, with this kind of tests, it seems that both horns are toast :(
With the bracket touching the - terminal, and a wire from the + post on the horn terminal, it has to sound. No alternative.
