As above, removed the horn and tested it, its working ok, iv remade the connections/spades but still not working, taken the steering wheel apart and all connections are present (Nardi steeringwheel)

where else is there for me to check? Fuse's? If so what ones and where are they located?

Got same problem with mine at the moment, mine is a newage and the fuses are in the engine bay

Jas Lad

Would anyone with a classic know which fuse or relay i should test with a multimeter to work out where the current is dropping

fuse for the horn is under the steering colum right side just change mine today think it was a 15 amp fuse

Jas Lad

are the relay and fuse in the same place? How did you pick which ones it was?

if you look closely you will see that its blown

Jas Lad

lol do you know which one it was though? It may not be blown but i want to test the wiring, is there not a relay also?

Do you have a multimeter? Or a circuit tester?
If so, get someone to press the horn while testing BOTH terminals at the horn itself.

On my classic, the fuse is under the bonnet in the fuse/relay box there. It's the RIGHT HAND one of a pair that sits in the centre, furthest from the roadside, nearest the washer bottle and is a mini-blade rated at 15A.

I don't know if there is a relay.

Jas Lad

I'll get a test light and give it a go, il try pin point the fuse also!

Jas Lad

Couldnt just work out what fuse you meant so checked them all, they are all ok, can you point it out in the picture then it'll allow me to see if the circuit is getting to the fusebox atleast

That looks nowt like mine, sorry.

Have you checked that the horns are getting current, yet?

Edited to say: the blue 15A fuse at top, 2nd from the right, has obviously been replaced at some time. I'd have a closer look at it, maybe even replace it with a KNOWN working one.

On mine, apparently the hazards are on the same fuse. Do THEY work?

Jas Lad

I'll check the hazards work, think they do, iv read every thread on here about horn related issues and theres meant to be a red relay hid up behind the steering wheel area which i'll have to look into.

I'v not checked the current yet as I couldnt get my mates tester, but getting it tomorrow, I'd love to be able to sort it myself without paying an autospark for such a simple thing!!

Those relays up there are a PITA to get at. You can see them, or feel them, but NOT both at once.

Jas Lad

hmmm i'll get a nosey later, getting a multimeter also

Jas Lad

OK got somewere tonight, found the relay, took it apart and one of the connections was broken, when I manually operate the relay the horn works, however pressing the horn button on steering wheel has no effect, is this because the relay is broken?

I'd say so, yes.

A relay is just an electromagnetic switch. It is used so that the horn push etc can operate using only a small current, so having light duty wiring, contacts etc and that heavy currents can't burn the horn contacts and cause the horn to stick on.

The light current from the horn contact flows through a coil in the relay, to earth, causing the coil, and it's soft iron core, to become a magnet.
This, in turn, attracts the soft iron sprung armature, which pushes the heavy duty contacts closed, allowing a heavier current to flow to make the horn work, typically 10-15A.

You'll want a standard on/off relay, take the one you have already with you when you go to buy, as they have differing terminal positions, and you want one that's a straight replacement. Car shops, HellFrauds etc, probably about £4.

Jas Lad

Good job, so basically as the connection is broken it was only working by me manually creating this... get you now, it's an odd looking 3 pin red relay, funny feeling it'll need to be from a scrappers, but i'll try the local motorfactors too
