Horn Sticking

On mine......if you use the wrong holes in the horn ring mounting or button mounting the horn stays on all the time
move the bolts or turn the spring horn press button round 1 space and the horn doesnt' stay on all the time. i.e the position of screws and or the postion of the switch can put a set of holes in line with the boss holes, that make it seem like the horn button is pressed all the time.

yours may differ.. mine is australian 1971 with tuffwheel and the padded centre push horn. it uses the US part as the "sprung" horn push. pressing it shorts 1 part of the switch to earth completing the circuit upside down or in wrong place and the circuit stays completed all the time..... Beep.......
