Airhorns prob

Forum: 

I have tried putting a set of triple airhorns in my Sportrak. But i have it all hooked up to a relay, and double checked that. But the wire I connect to the existing horn. No matter which one instantly sets the horn off. Which is very bad as my head is normally about 12" away at the time and makes your ears ache after a couple of times!!! I was wondering is there anyone else who has hooked one up and know which colour the wire is that its connected to? The guide on the site (not originally written by me) doesn't specify which of the 2 wires it is.

Lurch, try connecting one wir

Lurch, try connecting one wire to + of the air horns, and the other wire to -. Its stupid, but Daihatsus had stupid wiring that means that both sides of a load are live, even when the load is not in use. The two + cancel each other out, hence the load, what ever it is, doesnt work. Operating the switch, actually disconnects the + to one side, and makes it work. Im not sure what this type of system is called, but it is the reason some people have problems connecting spotlights. I connected the two wires to my solinoid air horns. The work fine.

Just a quick point.........

Don't forget these things are an instant MOT failure if connected to the main horn switch, overriding the fitted equipment.

Maybe just wire into a sprung toggle switch and save some aggro?

Daihat's do have a tendency to do wirring diffrently on every car they make, so don't hold your breth. However every Daihat's I've wired airhorns into has opperated on a switched earth sytem (i.e. power goes battery, horn, switch.) This requires conecting the relay up diffrently. Are you sur you've followed the right wiring instructions?

Any veiws expresed in this thread by me are purely from my own experience, and (sometimes) falible memory. Hope my comments help, but please don't take them as gospel.

I followed the instructions in the box with the air horns. Where the relay is connected to the wire(s) thats connected to the horn. As both of the wires are live then the airhorns go off instantly when its connected. Brundy seems to make an interesting suggestion but I don't fully understand it.

But at a guess you are making a similar suggestion?

Lurch, You should have two wires on your Sporty. Both Live. And you should have two terminals on the air horn compressor. Connect one wire to each of the two terminals, making sure you dont earth the body of the compressor to the car, (lay on plastic or rubber) Dont have either of the terminals grounded to earth. See if this works. If it does, then try touching the compressor to the car. If the horns dont go off then, but do when horn button pressed, you have it made. Forget the relay, and the wiring diagram that came with the horns. They are for "normal" cars

Thanks I think i understand what you are saying now. Connect each of the 2 positive terminals on the original horn to the + and - on the airhorns compressor, but make sure that its not touching the bodywork at all at first? Then to touch it on the bodywork to see if it goes off or not. If not then test the horn button?

Lurch, you got it. If the horn only goes off when the button is pressed, with the compressor eitheer earthed, or not, then you have it made. If it goes off when the compressor is touched to bodywork, without the button pressed, you have a problem. You would then have to mount it somehow, insulated entirely from the bodywork. Oh, and a suggestion, so you dont get deafened. Pull off the air pipe to the horns when testing compressor operation. You will still hear the compressor working, without the blaring horns.

Tried it and nothing

I tried doing what you advised. Connected both to the compressor. Tested it by touching it to the bodywork and thought! Yay half done. Connected it all. Tested it with the horn button, and still nothing. Whats the next step? Is there any other way I could hook it up?

Lurch, have you checked the f

Lurch, have you checked the fuse. Perhaps the compressor is too much for the original horn circuit, and has blown the fuse.
Alternatives I can think of are, as suggested, wire them up to a completely different switch. Or,
Use the relay. If the relays over there are similar to here, small plastic box approx 1 x 1 x 1 inch, rated 12v 30 amps, with 4 spade terminals numbered 30, 85,86,and 87, where 85 and 86 are the relay activation terminals, and 30 is the power, and 87 is the load, this is how I would do it. Connect your original two horn wires to the terminals numbered 85 and 86. Now check for correct operation by pressing horn button. You should hear the relay clicking. If so, Feed power from the battery through a seperate fuse to terminal 30. Take a wire from 87 to the + on the compressor. Take a wire from the - on the compressor to earth. That should get it working.
Sounds like you are having fun. Just out of curiosity, are all air horns MOT failures there, or just musical ones. As far as I know over here, single, dual or triple tone air horns are legal as long as all horns blast at the same time. Musical horns, the ones that play a tune, are illegal.

The normal horn still works,

The normal horn still works, just doesn't trigger the airhorn. The relays are exactly as you describe so I will try your method with the relay. Heres hoping!!! The relay I have has a built in fuse slot so you not have to put one inline to whatever you are connecting it to. Which i thought was very handy.

I personally thought that the law was the same that airhorns were legal as long as they all blew at the same time and didn't play any dodgy tune. Though if have it wired up via a relay would just need to disconnect 1 wire before the MOT anyway. I did that for my spots before went for my MOT a month ago.

Still not working

I tried the relay setup you said and it is still not working. It is starting to annoy me now as I was sure it'd work. Damn Daihatsu for using strange wiring techniques!!!!
