air horns

[ianf]

Can someone tell me whether there's much in putting a set of air horns in an VS ute, (do I have to pull the dash out?, and ifso, how????{I've had nothing but trouble with the original horn in that one minute it works, then it doesn't?, I've put a new one in but it to only works sometimes so I thought I'd go with airhorns as a filler???} Cheer's Ian

its only a basic wireing job. -ve wire to a good earthing point. then the +ve wire goes into a switch(generally a push button) then to a +ve source. i usually use a wire in the fuse box so a fuse is already in the circuit.

Since you have replaced the horn and it still doesn't work sometimes I would suggest the problem is at the hornpad or clockspring.

.... or maybe the relay - weak coil or burnt contacts ....

Be careful with the wiring as I think (THINK) that the VE like VZ is Negative Earth. You will have to re-think the wiring to and from the relay.

Tell me more about the coil & contacts?, I had a bloke at Utratune tell me my coil was not well?, not that him saying this means anything but now that you've also thrown it into the mix I'm starting to wonder???

There worth bugger all, just by a new one and replace it, you cant repair them. Or swap it with another one to see if your horn works with another relay.

Sorry Mate, I'm talking about the "coil" inside the relay. I'm pretty sure any Ultra Tune bloke would have been taking about your ignition coil.

See, a relay has a coil in it - that's how it works. A relatively small amount of current flows through the coil in the relay, and the electromagnetic effect pulls on an armature - attached to the armature are contacts which can handle MUCH more current. That way you can use a switch that has a low current rating to control a load with a very high one.

I'm pretty sure you'll find your horn relay under a cover on the drivers side under-bonnet, forward of the wheel arch. It just unplugs, and a replacement isn't expensive even if it doesn't help. Or if one of your mates has a similar car, try his relay - if that works, then you know!

piece of cake!!!!
fitted airhorns under the hood with an relay (fused from the battery to the 30 pin) but instead of earthing the relay (pin 86 or 87 me tinks see diagram on relay) i hooked it up to the wire (from the factory horn)that is the earth wire through the horn button on the steeringwheel.

:

its only a matter of language, but to speak in terms that wont confuse anyone, refer to the coil in the relay as a solenoid.
In combination with the iron core that goes through the centre of the solenoid, this then is known as an electromagnet.
Older oil filled ignition "coils" with their primary and secondary coils wound in solenoid fashion could also be obviously referred to as solenoids, but no one in the motor trade does.

Not sure what you mean here, negative earth is what all our cars have, except for some older british cars etc?

The contact in the steering wheel just makes a connection to the chassis so current can flow through the solenoid in the relay?

the only thing I can think of is that BenBoy was refering to the switching of the horn. The wire from the horn to it's relay is negatively switched...Perhaps thats what he was talking about?

oops, essentially what you just said. lol

[djeyecon]

i pulled my air horn kit out of the box....








then booked in with my auto sparky haha.
