Golf horns are not 12v then

Good if you want to sound your horn in 10 hours time

 

so how did it go

 

Hard to believe that both of them are duff at the same time.

Are they earthed of the mounting bracket? Worth taking off & cleaning up, mebbe.

 

Connect them to the battery then a nice tap with a hammer and then they should parp back to life. If not, you could always hit harder with the hammer until you feel better.
