1980 Puch Maxi horn wiring

Good morning. Again I ask you to bear with my lack of knowledge. I looked at Wiki pages and read about blue/black wiring to horn and brown ground wiring. I realized there are no wires coming out of my horn. I am attaching some pix- could the covered wires I am holding be the wiring I need to plug into the horn?

Also is there a way I can hook up the horn to an old External battery just to test if it is working? If so, what voltage battery?

Thank you!

Get a low cost multimeter or a battery powered continuity tester and test the wires with it. learning to read a wiring diagram will really help a lot.

Did I forget the pix? Think I did:


Re: 1980 Puch Maxi horn wiring

Someone bypassed the horn. pull the wires out of the adapter and see if they still have the female connectors on them then plug into the horn. Bet the switch is bad and they did this.

another idea- get on Amazon and get a $13 lithium horn- very loud and rechargeable USB port. Makes several obnoxious sounds but effective. Hooks to handlebars with vinyl straps, no tools needed

Update- neighbor came over and we tested circuit. We plugged black/blue into horn along with brown ground wire. Bike started and so did horn continuously! We took wires out of horn and that killed engine! I guess the wiring is all messed up. Here are a couple pix if the wiring hub- that’s not original correct?. I’ll have to refer to wiring Diagram on Wiki and check all circuits... oh well. For now lights work... can buy horn on amazon ....

The circuit needs the horn plugged in or the by-pass for the ped to run. Check the switch.

Puch has the horn in the ground side of the primary ignition circuit. The horn switch is a normally closed switch.

The switch is wired in parallel to the horn.

Under normal operation the primary side of the ignition gets its ground through the normally closed horn switch. When the horn switch is depressed, the circuit gets its ground through the horn, which produces that annoying gurgling wheezing sound From the horn.

If the horn switch is bad, the horn will sound continuously.

Just leave the wires as they were and yell at people if you feel the urge to.

"........the horn makes that annoying gurgling wheezing sound."

Thank you Blaine. I just brought my Maxi back to life on Halloween ( IT'S ALIIIIVVEEEE !!!! ) and the horn works, but I thought, "Jeezopete !! Is it SUPPOSED to sound like THAT ????"

Apparently it is. I was going to try to describe it as The Roadrunner when the Acme anvil finally landed on it, but annoying gurgling and wheezing pretty much nails it. Also you kind of can't hear it over the sound of the engine very much, so what's the point ? I'm just pretty jazzed that I brought the bike back to life. It’s kind of a beautiful little thing, and everything works. Even the horn - with it's annoying, gurgling, wheezing, roadrunner after the Acme anvil lands on it sound. I kind of love the sound of the horn. In the words of Gen. Patton, "God help me. I do love it so."

Thanks, Blaine, now I don't have to try to make it better. And a great big thank you to all of you who have been so kind to answer questions and offer the most helpful tips and advice and encouragement.

Why do we make this all so complicated?

Brown wire in grounded!

Yellow Wire is 6-12v supply

Green 🟢 is the switch
