I wired up my original 6v horn in my 12v system with a 10w voltage reducer and hit the button- nothing. I then tested the wire running to the horn and found that the reducer was not doing its job and I was getting 12v which lead me to believe that I must have fried the horn so I took it off and tried it with the 6v battery in my F*^d 9N and it worked fine. So my question: Are the voltage reducers directional like a diode or is this brand new one just bad? Why will the horn honk on 6v but not do anything on 12v?
