Howdy. All horns will go off as soon as power is touched to the one and only terminal . This means your horn wires are hot all the time. This means your horn relay is stuck, or a short to ground at your horn ring or between it and your horn relay. The relay gets 12v and is looking for ground to close [ horn ring on wheel ], which then sends 12v to the horns... To test the system without annoying your neighbors, unplug the horns and hit the horn ring. You should hear the relay click. Long Live Christine |
