all parts required for Dax 6V circuit

my question is that I have the 1985 Honda Dax ST70 6 volt version and my horn dosent work I would like to find out what are all the parts needed for the horn circuit please.

As I see it, you have the horn, horn switch, feed live wire and the return earth wire. Con check the two wire with the horn button depressed. If you have continuity, then the horn is at fault.

Thanks Pete will do.
