Have run 12 volts to both 6 volt starters and horns for 45 or 50 years. Never had a horn or starter burn up on 12 volts! Starts heck of a lot better and horn rattles the front fenders and hood! It does get the other drivers attention! Bought my first 47 Chevrolet in 1955 at the age of 13 for 35 dollars. Drug it home with dads trusty 48 Chevy truck.The first time I tried it was nervous as a prostitute in church about burning something up but never did! Still playing with all this old stuff at 66 years young!
