Horn problem

[lutronjim]

Horn quit blowing. Grounding horn button pin on relay sounds horn - so must be in column. I took contact parts out of the wheel and there was some rust which I cleaned - still wont work. I checked spring loaded button with a dvom to the connector and got 67 ohms - I would have thought it should have been below maybe 5 or less. Is 67 enought to trigger relay?

I then thought maybe I assembled contact wrong - read many post. I put spring disk on wheel raized center up, then the cup, then plastic retainer through the holes and then screwed down. Spring disk appeared centered.

Got to looking at the assembly and I dont understand how it works. The spring disk get a ground from contact with medal hub in wheel. The spring loaded button connects the relay to the spring disk - looks like it would blow all the time.

What am I missing?

Thanks
