Installing twin air horns on motorcycle HELP!!!!

Hi 
I own a Kawasaki ER5 and I am finding it difficult to have both horns working.
I have used the original horn wiring 2 wires to a connector block with 4 wires coming out to each horn. Is this wrong? if so please give me some instructions (that I would understand) how to install correctly please 
Thank you
Darren

O that's good. Looks really nice. I also recently purchase a set of truck horns from http://www.pbmissions.com/

This is a real old thread but it would have been much better to fit a relay from battery to horn + side then use horn button to control relay. Using horn button directly can burn it as it was not designed to carry high amps
I was having same issue with my train horns..your discussion proved problem-solving for me.thanks for sharing your knowledge.

Ok, are they "air horns"? If so, do you have a compressor for them? If they aren't air horns, then how are you wiring them, in parallel or in series? If in series you may have a bit of an overload problem.
If in parallel, then one of them is wired incorrectly. The button or switch must make connection to the power to the relay that then connects to the horns (hot wire) while the ground side can go directly to a chassis ground (IF your bike is negatively grounded....most are).

They are air horns but run off electric (no compressor). The bike had 1 horn origionaly with 2 wires going to that horn. i took those 2 wires and put them in a conecter block with 4 wires coming out so both air horn has 2 wires going to them
A test that would tell you a LOT would be to have your motor cycle running, and the headlamps on: have the horns wired up and press the button. IF, as before, only one horn blows, AND the headlamps dim, you are drawing too much power for the wires and fuse involved.

Can you sketch a circuit diagram of what you've done?

Yes i will try and produce a simple sketch and i will upload it in the pictures.
I'd be looking for something like this:

Yes that is what i have got but I cant get them to work they sound like they want to.
As soon as you press the horn button the horns make a small noise (not horn noise) for about half a second then the fuse blows.
