right then..... ive made up the loom everything works perfect apart from the horn, rather than the normal tone its a horrid screching noise and starts and stops even though i got my thumb on the button.... i plugged it into the light wires which i know work 100% as the head light is bright as hell on full beam (35watt H4 bulb) and its still the same, i wired the horn to the car and it worked perfect do i know the horn is fine, wires are fine so only thing i can think of is the horn dont like AC power well something along those line's

this is the horn i bought last november just didnt use it till now

You're right, the horn won't like having the ac on it, it really needs dc.

Few ways round this, but not sure which will work best, cheapest etc.

Fit a rectifier / reg which will give you the dc you need, but unless you make one can't see this being cheap.

You could solder in a capacitor in parallel, which may smooth out the ac, but you still would have to get the revs right for the sound, cos a stator pumps out more volts the faster it spin

Or you could try a 6v horn on it, which worked for me on an old Ktm, which blew the r r.

Just be careful, cos unless you get a r r on it, you could be over loading the stator.

Google Ricky stator, there is some good info on there how they work.

ive had a 6v horn on it in the past and it sounded the same as this one, i thought rectifier / reg was for bike's with batteries and regulator was for bikes without,

The reg rec will do that, convert the ac to dc rec, & also regulate the power to 14 ish volts, if you put a meter on your stator with it running, you will get about 6 v to 60 v from tick over to full revs.

If you start to run elec items off of it, you can over heat the stator and also, most stuff needs a solid voltage, normal about 13 v, again dc.

Bulbs ( lamps ) don't care wether it ac or dc, but if the supply isn't regulated you may blow bulbs.

The thing with the 6v horn works for some things,depending on the stator output. Other option maybe to buy a 3000uf capacitor from rs and solder it to the live side to the horn. May work.

Hope this is some help

That's similar to the regs on older ktms, it will protect your bulbs, by limiting the stator supply to 13 v, but it won't supply the dc you need for the horn, that def needs to be dc.

You could try making up a bridge rectifier with a couple of diodes, they about a £5 on eBay, and see if that would work. Only prob is it would get bounced about a fair bit.

Did you try running the 6v horn direct from the stator output?

Easiest solution is to get a battery powered horn
