    This is about as far off topic as it can get but I've seen a number of posts from guys who obviously are familiar with autombiles. A 1929-30 Ford Model A horn has devolved into my hands. I would like to get it operating again to give to my grandson to use as a noise maker at his school's football games but of course it is 6-volt and 6 volt batteries are about as common as chartreuse unicorns. I dimly remember hearing about a way to use a 12-volt battery by running the current through some electrical device that steps the current down to 6 volts. Any one know of such a procedure and if so, exactly what parts are required and how are they wired?

    Thanks.

    I'm not so sure about the battery being hard to find... A 'gel cell' would be perfect - no risk of leaking, small, less weight, etc.

    Found this one in about 20 seconds with Google...

    Here are some more

    I've got an old mid 70s Yamaha dirt bike that uses a 6 volt battery.
    Got a new one for it at "Batteries Plus".

    "Amazon" has a bunch of different 6 volt batteries too.

    You can also center tap a 12 volt battery. I saw that done some time ago when a person had a 6 volt device in a 12 volt car. He just found the middle connector, and ran a sheet metal screw into it with the wire attached.

    Yes, I know, it's tacky. Just an interesting fact is all.

    Go to your local Home Depot or Lowes and get a 6 volt dry cell lantern battery!

    Ditto on the Yamaha 6 volt. I have a ' 74 DT360 with 6 volt system. I replaced the battery early this year. Was $12 from some on-line store. They are small and light that would be easy to carry.

    Is the horn in good shape with it's original Sparton name tag on it? It may be worth more than you think. I would check E-Bay and find out.And buy a cheap replacement 12 volt AH OOOOGA Horn
    for the kid.

    6 volt batteries are fairly easy to find, Tractor Supply generally has them, they still use quite a few on antique tractors

    Get another 6-volt horn and wire them in series.

    While like others, I would use a 6 volt battery, the thing you were asking about is a ballast resistor. When some cars went to 12 volt batteries, they still used 6 volt ignitions. It is a ceramic housing with a coiled wire inside. I have no idea where you might find one anymore, but a junk yard would be high on my list.

    One of those old resistors burned a buddys car up trying to do the same thing. Get a new 12 volt one from Pep boys about $20. Jeff

    When I was looking for an original Spartan horn for my model A, used ones were about $200 and most need rebuilding. Eventually a friend of mine found one on a junked-out clown car at the dump...it was a Spartan, and it works and it was free.
