Panhead NOS Horn from 6V to 12V

[mrupp]

Hi this is Michael. I am currently finalizing restoration of my 1957 Panhead. I rebuild already alternator and regulator from 6V to 12V. Do you recommend to rebuild also the horn from 6V to 12V? Should I use an resistor or rebuild the coil (double windings, diameter half)? Or just use it like it is? Do you have any experiance or recommendations? Thx Michael

My 62 is 12v and I am using a 6v horn power pack, no issues, 7 years now. The small amount of time the horn is activated doesn't seem to affect anything. The grandkids sure put it through a workout, if it can survive their abuse you're good to go IMO.
