1926 Model T Horn Rebuilding

Who is a good rebuilder of horns? I have one that appears to be in good condition but I cant get it to work. Any contact information?
 
I'm not sure if the '26 had a magneto powered horn. If it is a mag. horn it won't work on 6 vts. DC. ( the mag. puts out AC current). Also check it it has more than 1 terminal or electrical connection. Some of them (depending on manif.) did not ground thru the horn body and need to be grounded thru this second terminal. Hope this helps. Power path for a mag. horn is: from the mag. terminal at the junction on the firewall, through the horn button then to the horn. Ground wire, if necessary, goes from the horn to the eng. block.
 
After thought: If you have a model train transformer with an AC side it can be used to test the horn.

.Try this guy on Ebay, he sells a lot of restored horns.

I thought that the mag put out direct current but I could certainly be mistaken. I tried testing it with a 6V battery charger (AC current, right?) and nothing. Maybe I am just electrically challenged, which I will freely admit. Over the years I have found it wise to hire someone who knows what they are doing with this electrical wizardry.

This horn has one terminal and is similar to the one I have on my 26 coupe. Did they make both an "electric" and a magneto horn? If a magneto horn apparently it will only work on magneto, right?
 
Greg the magneto puts out ac voltage ac means alternating current DC means direct current. A battery charger is DC . Yes they made both magneto horns about 16 V AC and battery horns 6V DC. The magneto horns were used on cars without starters as far as I know. As far as I know an magneto horn will not work on a DC battery. To use AC power on a DC device, you must convert to DC via a rectifier.
