horn relay?
in the middle of making a new loom for the bike do i need to use a horn relay for the horn or can i just run a positive wire via a button for the horn?

Re: horn relay?
Normally they work by switching 12v onto the horn.
So you would run the 12v to the horn, then complete the circuit running it to the switch. Can't ever remember seeing a horn run through a relay.
Best way to check is to mock it up on the bench with a horn, switch and battery.
Give me an hour, will check on my road bike to be sure ( no, I'm not Irish! )

Re: horn relay?
Your reg/rec will change your voltage to DC. Just wire as HD says. No need for a relay.

Re: horn relay?
Right, here goes, from the neighbour who knows, modern sports bikes use a relay to switch twin horns which are high output ( noise ) using a big current.
So they are wired direct from a big output such as a battery, with heavy cables. The switch, which is usually small & compact, simply opening the relay, which switches the supply to the horns.
For a single horn, which is just fitted as a mot requirement, to a dirt bike, where youreally don't care about how loud or powerful it is, you can run the supply, or complete the circuit, via the switch on the bars, so no need for a relay.
Unless of course your from Bridgend & want a set of Air horns playing the dukes of hazard, then you will need a relay & probably a small compressor too
Make sense?

Re: horn relay?
Ah, I thought you said before you were from this area, in that case you probably have the air horns already fitted, along with the cow horn handle bars complete with bar tassles ( I use my wifes old nipple tassles for my bike )
When are you giving the new improved version its first run out?
