Hooked my battery up and the relay starts ticking away. Well ,I have my horns unplugged, and its a new relay. when I plug the horns in ,they go off.
This problem means I,m grounging something right.

Where do I start to look. Thanks
67 Chevelle SS

this happened on my 68-malibu, the problem was the horn buttom was sticking on the steering wheel causing the horn to blow. check yours for proper operation with a voltmeter.(horn-unhooked).

curcuit is being completed (grounded) have you had the steering wheel apart? If so uyou may have pinched a wire to ground in there. Or you horn button itself is stuck.

Here is a link to a paper on how to diagnose a horn problem. It was written specifically for 1969 and later Chevelles but I am quite sure that the basics are the same. The 1969 column has several more wires coming out of the column compared to the earlier column with the crescent shaped connector.
