Personal experience. I did a zener diode install identical to the above link on a ZW, and had to reverse the track leads in order for electronic horns to work properly.

Then you used the wrong diode. You should use an Anode to Case diode with a 40 amp / 400 volt rating. THIS IS THE ONE YOU WANT. This is an NTE5991 Silicon Power Rectifier Diode.

Here's the procedure. The diode replacement process starts at 3 minutes into this video.
