Horn not working

[calummacneil0]

Has anyone got some advice on my horn not working at all from either buttons on steering wheel .

Have checked all fuses relays that I can see and all seem to be fine , connected horn straight to 12 v supply ant it works perfectly .

I am at a slight loss on this one any advice will be much appreciated.

A multimeter would help here (cheap and simple to use - I should have got one years before I did) as you could make a connection to the horn (+ve wire and -ve/earth connection point) to see if it is receiving its current when the horn button is pressed (you need 2 people for this obviously!). You may just have a poor earthing problem. The multimeter can then be used similarly to trace every part of the horn supply and activation circuit.

Maybe one of our leccies will have cleverer thoughts

OK lets see the circuit;

the fuse;

and the relay is F3-03;

The horn switch also feeds down the length of the steering column so there are several connectors involved there as well.

Hi Mike......I agree that a cheap multimeter is a great bonus when working on auto electrics.... ...BUT do not be tempted to use them on your house electrics..... ...cheap means cheap which are ok when working on 12V systems.....but if they fail on 240V systems you could be in for a shock....

My professional one cost well over £100 but it was part of my job...it can even be used in high risk areas...eg chemical envrionments.

The same goes for those neon screwdrivers which rely on a resistor to stop you being killed when you stick your thumb on the end.....

Electricity is a wonderfull thing...you can't hear it...you can't see it....you can't smell it...but if you touch it... ...by heck you will know it's there....

A very good point Alan, and something I was quite unaware of (although for some fortunate reason I've never imagined using my multimeter on 240v mains - a bit naughty these devices are being sold as suitable really though ).

Thank you for informing me/us of this risk. I'll stick to Bongos (I've had enough of house DIY these days anyway )

Many thanks guys for the advice , will give it a try and the pics of fuses much appreciated . Will post once I get it workin , best regards Calum

Hubby found that by following the wiring diagram that there was a break between the fuse and the relay and bridged in a new feed via an inline fuse. The relay sits under the headlight on the drivers side it is the one at the far left looking down on it. Hope this helps
