Fj horn

Just wondering what others have done with the horn when the car has been converted to 12 volt, is there a way you can make it work on the 12 volt system?

You will need to purchase a 12 volt horn. I don't think you can convert the 6 volt unit.

Cheers

You can have any colour you like, as long as its Fowlers Ivory,

When I convert the old Hondas to 12v I usually just have to get a 12v horn. The 6v one will work but burn out eventually. I have put the guts out of a 12v one inside a 6v one but it's a lot of work. Another way (if you want it to look original) is to leave the 6v one in place with some dummy leads on it and mount the new one out of sight.

All Good...no need to change any horns.
My FX has been changed to 12 volts (see Holenpedia or My Shed)
I have left the original twin 6 volt horns on running 12 volts...no problems, been like that for nearly 4 years.
IF you had any concerns simply use an old ballast resistor before the horn....this should step it down to about 9 volts.

The Horn and Starter would be 2 Items I wouldn't change after a 6 - 12 Volt Conversion.

Holdenpaedia, they're the brakes Mate.

They must be tougher than my old bike ones then. I've smoked them on 12v after about two blasts. If you're trying to stay original as possible what are you doing for a battery? Can you get one that will fit where the old one went?

They are tough.

One of the difficulties of 6 Volt Horns is getting them going. The limited Voltage was a problem.
In short the longer the Armature took to get moving, the higher the Current Draw which is why they were built so tough.

Under 12 Volts the Armature gets moving rapidly which allows the Back EMF to limit the Current Draw.
