May not seem like much of a victory however I will take it. The horn would not blow. 12 volts at horn and had continunity through horn. Removed horn and found Mud dobbers nest, cleaned and cleaned. Horn would not blow. Checked cleaned and adjusted points. Still no sound only a click. Soaked the horn in hot water and blew dry. TOOT. Yeah me.
