This horn has been refurbished. Can any one say for sure if it was done 6V or 12V? The person that did the rebuild did both but he has passed and we are trying to sell some of his stuff.

Just from looking at the picture, it appears to be for 6 volts. I'd try it on a 6 volt battery and see how it sounds. It won't sound the same by using a battery charger, but when I put my original horn on a battery charger it drew about 5 amps when the screw was adjusted for the best sound.

What Tom said.

Quick visual inspection will show 12 volt horns have more windings and smaller gauge wire than 6 volt.

dollar bill. Would not the 12 volt horn have more windings since it uses smaller wire. Long time ago, but when I wound mine for 12 volts it used 22 ga wire and the number of coils/windings was double the 6 volt number of windings. ken

Yes, twice the windings with smaller diameter wire for 12 volts

One thing I think you may be missing is, the horn will work with either voltage, it is only a matter of adjustment.

RawhideKid,

No, the adjustment screw will not compensate for 6V or 12V. For 12V voltage on a 6V horn, you will need to drop the voltage with a resistor or rewind the horn as the horn is just a motor that drives a noise maker.

FWIW- I did a visual with a known 6V and then hooked up each to my modern 12V car battery. The speed of the unknown horn made me pretty sure the rebuilt one was 12 Volts. Then in small red felt tip marker I see 12V on the new one!! Read the fine print.
