    The horn stopped working, took old one off put power to it, dead :cry:
    Anyway bought a new one, they have twin terminals so before fitting put
    power across from a spare battery all working OK.
    So fitted it, put the live to it first then the neg spade on, but horn sounded
    as soon as I touched it :Eek!:
    Put power across to other side still sounded soon as attached:Eeek:
    Any clues please :Smile:

    Horn Problems

    The horn button will connect / disconnect the positive supply or the earth supply to the horn. (assuming negative earth)
    If you check with a meter, one of the wires to the horn should be "dead" except when the horn button is pressed. Often there is a relay in the circuit - could be that this is also faulty.
