Horn

[Mikes57BuginPA]

The horn is not working on my 57.

Have already determined that the horn itself is shot. Probably from using a 6V V unit on a 12v system.

Car has an aftermarket steering wheel and I only see one wire connected to the horn button. One wire at the horn is always hot.

Plugged a good horn in and it didn't work.

What should I be looking for as I continue to troubleshoot??

Thanks

How did you hook the horn up?

Have you connected in a test light where the horn should go and had a helper push the horn button?

Have you looked at the wiring diagram for your year and type of VW?

The horn was hooked up this way when I inherited the car.

I had a test light on the other lead while a buddy hit the button. The test light did not light up.

I really have studied the wire diagram yet. Was hoping someone would have a past experience.

If the test light does not light up with button pushed, then you have a wiring or ground problem going from the horn to the horn button or even to the body of your VW.

Remove the horn button and run a wire to the test light and ground the test light to the metal inside the steering wheel. Does the light turn on?

Where does the wire to the test light get hooked up to?

Is the steering columns horn brush still in place? ...and if it is, does it have the brush & spring inside...

Make sure it's completely grounded. Mine would not work. Had to take off the clamp for the steering box make a bare spot on it and the beam. Then it worked.
