What gives, Hella Horn

[zooroadbaja]

I got a set of UFO(Hella Knockoffs) Supertone Horns for Xmas, I tried installing them today and ran into problems. I thought it would be as easy as cutting the old plugs off and connecting the wires to the new horns, but no sound, nothing. The original horns worked to.

I've tried running the horn straight off the battery to make sure they worked. I tried using a 30 amp relay as the Hella Diagram Shows and still nothing.

Also I noticed the Passenger side horn only had one wire running to it.

Any help, suggestions?

Here's where I'm at:

Hella wiring diagram I found, 2B is what I'm looking to do

Not sure how you had it wired up before, but you dont need the extra relay. The factory one is adequate. The factory horn has +12 V over the wire that you can connect to the horn, and then you can ground the horn locally through its mounting bolt.

I tried running the two wires on one and the single wire on the other, and got nothing. I tried grounding both horns to the bolts holding the horns and still nothing. I tried doing the relay setup and nothing. I cant figure it out. Any one local that likes beer and helping someone out?

Let me google that for you and get a voltmeter.

Or just copy what the OE horns were doing. I replaced mine and dont remember any mystery.

PS: ground via screw, power leads are power. Thats why the OE horn only has 1 lead running to it.

verify your grounding point.

I'd verify that with all your connecting and disconnecting and reconnecting that you didn't pop the fuse.

Figured it out. One wire was positive and the other was a jumper to jump power to the passenger side. It's always the easy things that stump you. Thanks for the help.

I have real hellas on my truck, I just used the factory wiring with some extensions that I made, and grounded to the hood release. Worked first try.
