Horn Doesn't Work
If the horn does not work, the horn switch may not connect the circuit from the battery to the horn.
Horn Stays on for a While
If the horn stays on, the horn switch may be getting stuck. The circuit completed by the horn switch may remain intact, keeping the horn on.
Horn Sounds by Itself
If the horn sounds by itself, the horn switch may be making contact with the electrical points randomly. This will cause the circuit to be completed and the horn to sound.
