I’m hoping some kind person can help. I have a 1983 KZ1100LTD. The horns do not work. When I hook a meter up to the horn leads and hit the horn switch I get a reading of 11 to 12 volts. When I touch the horns directly to a 12-volt battery they work. But when I hook the horns to the horn leads and hit the switch…nothing or a faint low pitched squeak??? This has me puzzled. Any ideas??
