I own a Model_ Horn. OOOOGAH. It is 6 volt and cars these days are 12 volts. Where can I find a way to hook it up?
I would be tempted to use a 6 volt “hot shot” fence charger battery and connect the horn through a separate push button switch mounted on the side of the steering column. The fence charger battery should be good for many “OOOGAH’s”. This will give you an independent horn circuit. Both the “hot shot” 6 volt dry battery and the horn button are available at most farm stores.
