Horn

Hi guys. I have an old Klaxon horn that came out of a Whip-it car. It's 6v. I've converted my car to12v. How can I hook this up and what do I need. I will use a separate button. Are there any diagrams out there or video's. Thank You.
 
Here's a basic wiring diagram of a horn circuit. It may be very similar to the way the existing horn in the car is hooked up.
I'm assuming you've tested the Klaxon horn and it works well.
Depending on what car you're working on (???) you can probably duplicate the wiring setup the car has for it's existing horn. You'll need a 12v horn relay and some 10ga wire from the battery to the relay, and from the relay to the horn. With smaller wire to your new switch.
Connect the new wiring to battery power as the last thing, if it sparks start over.

The Whippet car was a product of Willys-Overland. It was manufactured from around 1926 to 1931 or so. A horn from one of them would be in the same league as the Sparton and other horns for the Model A Fords. Those old motors may not be able to take a full 14-volts that a car with a 12-volt system would run at. A dropping resistor would likely be needed to slow the thing down a bit. I have no idea what would work best on it but you might contact Randy Rundle and 5th Avenue Internet Garage. He carries some dropping resistors that may work OK. Most of those old late 20s & early 30s systems didn't use a relay. They were generally a simple system with the switch on the steering column providing a ground path to operate the horn motor.

That horn may be valuable to old Willys fans but I don't know what they are worth.
 
What he said ^^^

(I've never had my hands on one of those, just a few old ******** type truck horns.)
 
I had an old 6 volt siren I scrounged from my Dad’s parts bin. It ran fine on 12 volts, really loud and high pitched. I’m sure if I’d run it for long I would have burned the motor out, but it was good for for a few seconds, and that was all it needed.
