Faulty electric breaking every new horn I put in LT31 -78

I have an issue with a broken horn, Ive replaced it several times but every time I install a new one it breaks with the first honk. I was thinking it might have something to do with the relays, do you think that could be it? are they breaking because of too much electricity? 
Ive tried to exchange the relays but couldn't find a matching spare part.

Im thankful for any input

  • The horn does not have a relay, just a fuse #9, 8A
    Checking the earth connections, testing the horn without mounting it and ensuring that the horn is properly compatible, 6V, 12V or 24V.
    The horn, or any other appliance, pulls electricity, so if it breaks immediately there is something wrong, since if it was pulling too much the fuse would blow first, saving the horn.
