    My horn again

    Jetfuel helped me with the horn relay connection. I got a brass encased spring loaded Riobi brush. Thanks. Now the problem is the steering column shaft. It isn’t well grounded on my car. As I turn the steering wheel the resistance to ground varies unpredictably from infinity to 12 Ohms to 0 Ohms. How do I ground the shaft?

    I had the same issue. I used the factory column with the air bag slip ring and utilized two of the wires to ground the horn relay.

    Is the “slip ring” the same thing as some call the clock spring? As you can tell, I’m easily confused.

    A slip ring would be a circular conductive ring with brushes conducting the electrical signal. this picture has 3 signals.

    A watch spring has wires that attach from the column to the steering wheel. they wind up when you turn the wheel. Take a look at this: https://www.motorweek.org/features/g...prings_airbags

    Yes it is the watch/clock spring! Not a slip ring. The original slip ring requires the ground magically happening through the column which did not work every time, there fore utilizing the hard wired clock spring. Thanks Bob!

    I simply added a spring loaded brush to rub against the steering shaft itself. Works great. I did have to make a retainer for the brush and screwed it to the column cover tube. I believe it was a brush originally used on a falcon steering column. Any spring loaded brush would work if you can fit it into your column.
