Hi, Terry first check for continuity at the power and ground wire at the horn, then check for continuity at the horn button, back in the day there was a small adjustment screw on the back of the horn, by turning it one way or the other you could set the limit on how much the diaphragm vibrated. For more information about your issue, please visit the websites below, and for specific information or questions, please feel free to contact me at xlch@mail.com. Good luck and have nice a day.

2007 Ford Explorer horn quit working?


suggest checking if 12 volts goes to horn wire at horn end when horn pressed from inside vehicle. A 12 Volt probe {google it} can be a cheap checking tool for this.
If 12v volts is switched when button is pressed {could be earth being switched if it is then place probe on constant 12 volts and negative lead on switched earth wire} then the horn itself is faulty.
If no voltage switched then horn relay needs to be checked. check if voltage at horn relay coil contact when button pressed.
if yes then relay may be faulty. if no then horn switch could be faulty.
you can check switched voltage also at horn relay switched contact when relay plugged in. To see if relay is doing what it is meant to do

Horn not working on a honda varadero 125


Use a multi-meter set to dc 12v take the horn out of circuit and connect the positive end to the horn supply from the horn switch and the negative to an earth point on the frame. Press the horn button, do you see the meter jump up to 12v when you do this?

Yes - Replace the horn assembly. It's getting voltage but not sounding.

No - Suspect that the wiring or the horn switch is faulty.

isolate the battery. Disassemble the grip Disconnect the wires to the horn. Set the meter to continuity test. Put the probes on the terminals of the horn switch. press the switch. Do you see the meter on the Multi-meter kick?

Yes - suspect the wiring between the switch and the horn assembly.

No - With the 12V side of the switch isolated from ground reconnect the battery. Switch the multi-meter to DC Volts. Connect the positive probe to the supply side of the switch wire and ground the negative side. Does the meter kick to 12Volts?

Yes - I don't know what is wrong. possibly an intermittent fault.

No - You have no supply form the battery. Suspect the wiring loom from the battery to the switch especially where it goes from the frame to the handlebars. You could have a break there.

My horn WILL NOT work


Where are you connecting the tester to? If you are connecting one lead to the negative terminal on the battery and the other to the horn wire and it lights up try connecting a wire from the horn housing (bare metal) to the negative battery terminal and attach the horn wire to the horn and try it. if that works the ground path from the battery to the horn mounting place is broken somewhere. you may have to run a negative wire to the horn mounting place to make it work properly. Hope this helps.

Rodeo wiring diagram


The wire to the horn button is a live wire and it is shorted out when you press the button. This activates the relay and blows the horn. relays normally work by power coming to a terminal through the coil and out the other terminal to earth . This connects the coil and so the contacts are pulled together to allow power from the battery though to what ever is the relay for .. So what you need is power to a coil terminal on the relay and the horn wire connected to the other terminal. This will complete the circuit when you press the horn and the relay will close and the horn will blow.. To get this it may be necessary to piggy back off the power wire ( battery terminal on relay ) to a coil terminal .

My horn on my Buick Skylark will not work. It blows every horn fuse we replace. How can I get it to work?


You may have a short circuit in your horn button causing the
fuse to blow when you press the button or in the horn itself.

1. Locate the horn under the hood normally in the front of
the engine compartment.
2. Once you locate the horn, disconnect the wire from the
horn.
3. connect a VOM (Volt Ohm meter) to the horn's wire.
plus(+) side to the wire and negative (-) side to ground
or some metal part on the car.
4, set the VOM to dc voltage and have someone press the
horn button. You should read 12 volts on the VOM, if
not you have a short in the horn button, if you do mread 12 volts
you have a short in the horn. Replace the horn....
