A Quick Look in the tech section will help you a lot, if stock the horn itself has 2 wires, one is full time power to it, the other goes to and up the steering column, that wire to the steering column makes the ground to complete the circuit and sound the horn. Your description of the parts in the steering wheel/horn button sounds correct except you do not describe the mast bearing/horn contact which centers the steering column (mast) in the outer steering tube, note the wire on it? And brass contact surface on top to make the ground? So… meter the wires at the horn, one should be voltage, the other should tone to ground. If you have voltage on one wire jump the other to ground and the horn should blare, if it does then follow the wire ground to the steering column and see if it is intact. Jumper wire from ground to mast bearing contact and the horn should blare, if not Then pry the mast bearing/ horn contact out of the steering column and see what you find. Chuck
