Horn - should it have continuity?

[Radek]

OK, so to check if the horn is shorted (that's what I'm really after), what should I measure?  It is honking, BTW and is not on the car.  When I connect it to to a battery, lots of spark is created.  The wire I touch to the battery terminal seems to burn a little hole in the terminal.
Thanks.
Radek.

continuity between the two electrical contacts.  I'd wager that if 
you applied 12 volts DC across the terminals the horn would honk.
