Stebel wiring problem

Okay I even got the pre-wired kit, and can't figure what's wrong!
Horn comes on as soon as I turn the key.

I just wired the fused pos red and neg ground to the battery,
and the blue to the brown/black wire that went to the old horn.

The relay is setup with the blue to the 86 connector on the bottom,
87 connector on the left goes to pos of battery,
30 connector on right goes to pos of new horn,
and 85 connector on top goes to neg of battery and neg of new horn.

Anyone know what's wrong?

The Gadget site reference above shows different hook up of the relay...

30 is fused 12V + incoming from battery
85 is the ground
86 is from the horn button lead
87 becomes hot 12 V+ out to the Stebel

Other than that, possibly your 'blue wire' gets 12 volts on it when you start the engine...and that pulls in the relay.

check the voltage on the blue wire while running?

If it is 12 volts, then it is not the correct wire from the horn button.... and you will need to find that.

Well I've tried a dozen times. Just as described.
Even tried the other relay that came with the wiring. Same thing. And my ears hurt

I can't find my circuit tester, but there's only the brown/black and black/white connected to the old horn. The black/white must be ground.

I just don't understand why it's doing it. The brown/black must be supplying voltage to open the relay circuit when the ignition is on. When it's removed from the relay, there's nothing. When connected to the old horn, it only sounds when the horn is pressed. I just don't get it.

Thanks all for your suggestions, though.

confirmed
85: ground (to frame or battery)
86: low current input (hot wire from oem/bike horn)
87: power output (hot to stebel horn)
30: +12V input from battery

also, found this posting by Jeep Pirate

Your existing horn wires go on terminals 85 & 86. It does not matter which order. Your positive wire from battery (with in-line fuse) goes to terminal 30. The wire to the air horn goes on 87. Then just ground the other air horn wire.

you need a voltmeter...
one of those two wires will go hot if the engine is running and the horn button is pushed. That is the one you want to hook to the relay base 86.

good luck

The brown/black to old horn is hot at 12v when ingition is on, testing with frame ground.
When it's hooked up and tested with the ground of the old horn it's live only when the horn is pressed.

Not an electrician by any means, but have you considered a bad relay, i work on computers all the time and have seen lots of new components dead or malfunction right out of the box, and they are much pricey-er,(is that a word)?

Just sayn. If I am out of line or offline please feel free to ignore, i do that a lot.

I have a grounding horn button system.
I had to run the blue from the ground of the old horn to 86.
I used a coil power adapter from the fused 12v to both 85 and 87.
The ground from new horn and battery are discarded.

Is my bike different from all the others? Is it a problem somewhere?
2 days old and not news I want to start with.
