I have a 78 honda express and the horn doesnt work...there is two wires that go to it, a pal green and balck. I figured out that the green one goes to the horn button and the balck delviers the power...The back wire will spark with it rubbing against metal and the green one will not. I tryed playing with the screws on the back of the horn but nothing. Do these things usually break?? How could i check if the horn button works? Also does anyone know where i could get a replacment??
also on the back of the horn it said SM-8 Knight Horn 6v 7 L or n i dont remember..It had a screw on the side where it said up and and another word but was rusted over..it did work some time ago but not that well and then started to not work..
