Looking to get some advice on my horn. I bought the car with an aftermarket steering wheel which did not have a horn button...anyways I replaced with a standard woodgrain wheel, connected the horn and no dice. I get some sparks and buzzing under the steering wheel but no sound.
When I go to the horn both the are wired in a series with Horn A before Horn B. Both wires have 12v going to them when I push the steering wheel button in and have 0v when its not depressed. I tested both horns and the surfaces of each have ground. These were painted solid black and the engine bay was repainted with the resto I am wondering if it has a true ground or not.
1970 Challenger with dual horns, two of the small black ones, adjustment knobs are very different on both on Horn A the screw is almost fully out while Horn B has the adjustment screw all the way in. When I apply 12v directly to the horns from an external source I also get no sound from them, is it possible these are bad? Can these short out or rot? To my knowledge these are original and 52 years old.
Thank you for the help!
