I replaced the upper mast bearing in my '46 last night and it went well until I went to put the horn button back on. At each step, I would hook up the battery to make sure there were no shorts. When I put the horn button on, no matter what I tried, the horn would blast. When I took it apart, the spring sent things flying and I wonder if there is supposed to be some sort of insulator between the spring and the button. Any advice would be most welcome. Thanks.
