Scooterotica

The only way to get a consistently decent horn is to power it off a battery, otherwise it will suffer if you have the lights on or running at low revs.

I'm totally lost now, are the links to work the horn or koso tacho? I realise the link to the actual koso regulator is for just that.

You can't use a regulator like those in the links to power a horn, they can't produce enough power. You can make a regulator pretty cheaply using four diodes and a voltage regulator ic for about 3 or 4 quid. Or you can buy the koso regulator. I'm happy to build one if you want to give it a go. Hope that's as clear as beer.

Sorry Dave . I think I took the thread away from your topic

That's ok Steve, no problems.
Eddiestone, if you would be kind enough to build me what I need that would be fantastic. I can send you some money with paypal as a gift to cover the costs. Perhaps a P.M with your paypal address and the amount. Thank-you

I'll check what components I've got and see if I can knock something up. You're not in a rush, are you...? Might be a week or so

Yeah I can wait awhile, please keep me posted. Thanks again
