The Stovebolt Site Forums The Shop Area Engine Shop Horn Relay Wiring

I'm generally pretty adept when it comes to wiring/electrical, but the horn relay hookup has me scratching my head. I've found information on how to wire the relay (left pole to horn, center pole to battery, right pole to horn button), but I'm stumped as to wiring the actual horn. It has two poles/connectors; I'm assuming one is positive (+), the other negative (-). However, there is only one wire leading from the horn to the relay. So...what hooks up to the other pole (on the horn)? I assumed it connected to a ground...however, when I do so, it completes the circuit and the horn sounds. I've tried every variation I can think of, but to no avail...at present, I've hooked up the horn directly, without a relay. However, I understand that's not the best (and safest) way to go.

Any help/suggestions would be greatly appreciated.

Thanks!

The relay grounds through the horn button. That closes the contacts & sends power to the horn.If the horn has 2 terms. yes you would ground one. If it blows you either have the relay wired wrong or it is defective. I,m not shure if it,s nessesary to have the relay grounded but won,t hurt.

The horns with two connectors do not use a relay. One is hot all the time the other goes to the horn button to ground the circuit.

I used a relay on mine, and I just made the relay ground through the horn button. I suppose you could just not use a relay but it seems like the intermittent connection might damage the horn button components quickly with such a large load going through such a delicate component.
