I know horn problems have been done many times.

I have a multimeter. My horns are getting 12 volts when i activate them. Can the problem still be the spiral part in the steering? I watched a youtube video a fellow on here did and it seems simple. I'm not a mechanic, but seems like they should blow it they get the twelve volts. If this is a dumb question, remember i said i'm no mechanic.

 

If power gets to the horn, then the horn is dead.
If no power gets to the horn, then something in the wiring (could be spiral cable, or relay, or a regular wire, or even the switch contact points in the steering wheel) is dead.

Make sure that the horn is both getting 12v, **AND** that the horn is properly tied to chassis/0V. It needs BOTH in order to work.

And if you are reading the voltage with a multimeter and having the wire *disconnected*... keep in mind that the multimeter only reads voltage, it doesn't read CURRENT. You can get a condition with wires and switches where you can get the voltage across, but it doesn't supply enough current to power the accessory. You should test the voltage while the horn is actually attached to the circuit.

 

You guys sound horny.

 

You sound like you're 11.

 

FYI my spiral cable was bad and my horn still worked. not sure if that helps you at all. is your airbag light on?

 

You need to have a Plus+ Voltage and a negative(-) return wire, usually to your battery negative terminal which
is also connected to your chassis as stated previously. I assume you have a switch wired in there, so make
sure you have the right type of switch...again assuming, it would be a Normally Open switch that when you close/activate
it, the horn sounds....oops sorry, i thought you were adding another horn...
so disregard the switch statement...wiring methodology still applies though.

btw a multi-meter does have an ammeter to measure current, (why it's called a multi-meter)

 

His guidance is good. Listen to him. If the horn is getting power then nothing is wrong at the steering wheel.

Some DMMs have amperage on them but most do not.

 

Thanks for the input guys.

 

Gave me a LOL

 

The "spiral cable" has two ribbons, each with about 8 conductors (going on memory on the number of conductors). Any one or multiples can fail, impacting only the functions that run over that particular conductor. Just because one conductor fails doesn't mean that any other will also.

 

already knew this
