Rick,

Welcome to the forum, more than likely your horn relay is bad. Here are some things to do to trace your problem.

First identify the 3 wires going to the relay, one will be going to the horns, another will be a 12 volt non switched source and the third will be the negative from the horn.

Once you id the wires supply 12 volts to the wire going to the horns, the horns should sound, use a volt meter to check the 12 volt supply on the relay, if good then place the positive lead of a volt meter on the positive post of the battery, place the negative lead on the wire going to the horn. Push the horn button and the meter should read 12 volts, if it does not read 12 volts your problem is in the steering wheel switch, if it reads 12 volts the problem is the relay. Use a piece of wire and supply negative to the negative terminal on the relay, if the horn sounds the relay is good.

The copper rivet you are talking about is spring loaded and contacts the bottom of the horn switch, you will see an indention on the bottom of the switch. The round spring loaded disc that looks like 3 layers of ceramic is actually the switch. It mounts under the steering wheel nut and when pressed closes the contacts suppling neg to the horn relay through the spring loaded rivet.

Good luck,
