Black wire that runs through steering column is a ground. Check the small spring in the steering wheel area. This spring is usually missing, or broke. I've seen folks use springs from a pen to replace; they usually work well. I've also seen where folks try to jury rig a coiled wire or other methods to replace that spring that short out, but this usually makes the horn blow constantly.
If you have no continuity from this black wire to ground, check that spring and the black wire for breaks.
Never argue with an idiot; they'll only drag you down to their level, then beat you with experience.
