Fourtrak horn

Forum: 

Hi. I bought some dual tone electric horns(x2) for my 1990 2.8 F70 Fourtrak. I want to use them to replace the stock horn. The stock horn works fine. So I connect the 2 new horns in parallel and.....nothing happens. I can connect one wire and earth them to the chassis and they work, I can't see a reason why they won't work on the switch, I have power to the horns and the switch works with the stock horn.

Can someone please help me figure this out?

Thanks.

Problems With His Horn

Not a problem i would advertise as many will suggest Viagra, joking apart it could be the way your horns are wired.
Some Daihatsu models have a permanent live to the horn, the earth is switched through the horn switch, you will need to check this. If you have a permanent live then connect it to the live of your air horns, this should work.

Wiring in series means the horns are only getting 6V each instead of the full 12V, so it is not enough to operate them.

Mistake

When I said series, I mean't to type parallel, =/ Also, they are not air horns, just dual tone(2 horns) electric.

Thanks.

Have you tried just pluging

Have you tried just pluging the existing wiering into the new horns only? Do they work on there own? Have you pluged the wires in the right way around? Just a couple of thoughts...

I plugged in one of the new

I plugged in one of the new horns on its own and both in together and no success. I have tried the wires in all possible ways. I guess I will have to try a relay or wire them in on there own system with a dash switch.....

Something is wrong here !!

Don't like the new shape much.

This doesn't make sense.
Did the Original horn die on you and you are just putting on replacements?
If it worked and you are just replacing it then it should just work!!
If it was already dead then it sounds like something else Sad

Are you sure it is not the fuse?
Are there two wires?
Are you absolutely sure one of the wires is live when you press the Horn?
Are you absolutely sure the new Horn/s is not faulty?
I replaced my Sirion Horn (Because it was pathetic)for a pair of Electric Horns (Now sounds great)
I have looked at the diagrams I have and it's just a simple job of connecting up the two wires.

Sorry Stalin - Just doesn't sound right at all.

Check your circuits ok.

The old horn works fine,

The old horn works fine, hence me being at a utter loss. I'm a HGV mechanic, and I asked the blokes I work with, and we are all stumped. It just doesn't make any sense. I think I've heard that Daihatsu use double positive? I'll look again, but I'm sure I've checked it all more than once. Its damn annoying, as you might imagine. I am replacing it with 2 electrics because, like yours, its pathetic.

Cheers.

What a puzzle !!

Well if your an HGV mechanic you should know your stuff then.

It will be something really crazy.
There are Earths all over the Sirion and as I find them I take them apart and give em a good clean. Smile

But if you just put back your old horn and it works - Put the new ones on and they don't ?? But they work connected direct to the battery Sad

Criky - This is a good one.

I'm stumped as well.

Good Luck. Bob F.

Yes it is.

I'll let you know if I manage to get it working. Thanks for your replies Smile

Duel tones.

Just be aware that dual tone horns which give two distinct tones, are illegal. Such horns were banned several years ago. Police will stop and issue prosecution. Such hornes were banned because they sound similar to police/fire/ambulance sirens.
MOT will also fail on dual horns - not compliant with motor regulations.

Do what i did once, one of

Do what i did once, one of my old ones had a poor horn so i borrowed one of the spares from a locomotive, this was one of the rare 12v items. This shocked a few people the first time they heard it, particularly when sitting at level crossings, it provided many laughs.
