I have had my 64 for about 5 years, it has 57K miles. I noticed recently that the horns had stopped working when I pressed the horn and the alt/gen light comes on when you press the horn ring. The only thing that has changed since I bought it was I replaced the regulator awhile back. But havent used the horns so never noticed. Have replaced relay, checked horns by jumping them to a power source, both work. Took horn ring off and have replaced spring. Are there more then 1 spring in steering wheel/column on 64's. Any Idea's? Could regulator cause issue?
