Ducato Horn Problem.

[Channa]

Having got the indicator working. time to address problem two ....My horn doesnt work.

Let me tell you what I have done so far.

Firstly on the horn itself took both terminals to a car battery and it sounds, the problem is at the boss end..on the steering wheel a repair has been made before it seems.

fuse checked and ok,

The negative terminal goes from the centre boss of the steering wheel to the part of the terminal that remains in the boss.

It looks like the problem is the positive feed, previous owner had soldered a piece of wire on to the original feed and that in turn is attached to the male part of the boss ( bit you press to get it to hoot).

I have cleaned the wire and attached a modified block connector to tidy it up
I reckon my wire is ok ....using the mulimeter ( caps taken off) it shows a reading of one which decreases to 0 so the wire is not broken ?.

On the voltage side, I have taken red probe to the wire, and black to an earth and nothing happens does this mean I have a dud live.? If so it looks a bugger to get to so is there a shortcut.?

Any suggestions warmly welcomed.

Mot is in a month I suspect sitting in the drivers seat shouting at folk and using gesticulars will not get me a pass.

Did you set the meter to dc volts when you tested it for voltage, or did you leave in on OHMS. Have you tried it across the battery, The meter not the horn, did you get a reading. wher did you put the black probe, did you put it to something metal or just the black wire on the horn. when i say metal i dont mean your watch, i mean something coonected to the chassis. Where abouts are you in the country as this could have a bearing on the reading . Only joking if your in the northwest i could come and take a looksie,

Yes I put it to 20 on the dcv scale, I put the red stick to the live wire ( I use that term in the loosest sense) and the black one I put to the neg terminal of the boss ,( no reading) and then a metal bit in the middle of the steering wheel ( which the earth in effect earthes too) 0.000 the reading which makes me think the live id dead if i has done it right ?

Channa.I am told it is quite a common problem with men your age!!

Yep it sounds like you did it right. You have no voltage could be a broken wire somewhere round the steering column would be where I would be looking. Is it a centre horn?? sounds like it. try bypassing the switch see if it works but I doubt it if you have no voltage. If you can put your tester back on ohms and attach one end to the wire on the horn and the other to the end near the steering wheel see if you get a reading, you might have to use some other wire like speaker wire or something so it reaches. good luck.
Ps make sure the probes are not capped again.

Does the horn have a relay?
If not, the usual method of wiring a horn is to have a live feed to the horn (+) on one terminal and the other terminal is switched to earth (-) in your case using the steering centre boss. So the wire going to the boss should normally be open circuit, connecting to earth when the horn button is pressed.
If it has a relay, this could be different. In either case, you really need a wiring diagram.

Channa,

Did you have the ignition switched on?

Horns do not work if it is switched off.

 

[Boxerman]

Horns do not work if it is switched off.

Don't put any bets on that

[runnach]

boys a brownie point ...I had the ignition switched on

 

[guerdeval]

If it requires a new complete stalk I may have one, I bought it for a '99 model but it was for an older one.

So when you press the horn a circuit is complete and the horn hoots ?? that makes sense looking at it.

bits of copper make contact, a circuit becomes complete and the horn honks
when depressing the centre boss.

What is making this situation slightly more difficult is the previous owner had done a bodge,,, I think i am attempting to fix a long term problem.

It actually is making sense and confusing at the same time...I will take piccie stomorrow and let you see.

I suspect that the wires have been swopped live to earth , earth to live as part of the bodge. the wires are far longer than need be?

Without writing an essay perhaps pictures will be more useful.

But has things are the part of the horn embedded in the boss is a negative...the part depressed is the positive and here lies the problem with a live feed ? for some reason the live feed was disconnected from the depresseing part and left to its own devices on a metal boss beneath the steering wheel

Let channas challenge Honker begin

Hi Channa
Just a thought if you think it was a bodge try resoldering the joints as you may have 'dry joints' from the previous soldering.

never mind 'bye for now Freddie' ....what is a dry joint ?

I feel the Cabanon Elise ( for sale making an emergency re emergance !!!

Contrary to some assumptions expressed here, some of us are technically thick as two short planks, I for one far from embarrassed by admitting I dont understand the basics.

Has per my caps on the probie things on the multimeter post quite happy to look daft.

pray explain

Hi Channa
Dry Joint, when you solder if the solder does not flow onto the recieving metal properly because it was not hot enough or it was dirty with grease or similar then you get whats termed a dry joint, there is in fact no electrical contact between the solder and the recieving metal.

Cant wait to see pics. will let you know if i can help, however dont hold your breath.

Greetings M'lud,
Most modern horns use relays in the circuit as the horn requires a large amount of power to work. Thus there is a high tension circuit and a low tension circuit. In order to diagonios the problem you need to follow the following instructions.
1 Study the attached diagram carefully and then relate it to your vehicle.

2 Using your newly aquired toy (sheath free) check carefully each component of the circuit, and repair or replace faulty parts.
3 Congratluate yourself on a good job jobbed.

Hi Channa
Sorry I did answer that soon but I think he answered the question very well indeed (well done that man)


Bye for now again!!

Flippin eck !!...I was wanting horn help not them hiroglfiic things

I has studied the diagram and I can see a Pisces crossing the world of Taurusbut sure I is not interpreting fings as intended.

I mustnt succomb to a garage bill, and will try harder !!

Pretty sure it is at the boss end I fink a few photos may help

Hi Channa
Sorry you got that wrong-- it's all about Mercury being in retrogade motion at the moment and the moon being in Leo!!
Re the 'dry' joint I did not want to come over as trying to tell you how to suck eggs. Sorry about that.. Good luck with the problem

Listen Freddie, I assure you far from upset or a feeling of being patrronised.

I would far rather with the collective mickey taking and advice of you lot, sort it myself that way I learn summat
