Similar to the Model A I had a while back, I had to take the back cover off, light oil on the wick, and making sure the workings spun freely. Shorting out the horn at its back, got it to spin, but no dice on the horn button. Tried adjusting the top screw on the back of the horn, but I wasn't sure how tight or loose that has to be. Pulled the horn button out and cleaned the two prongs that go into the column, and still no contact. A small wire coming out of the base of the column near the steering gear, looked like a connection that comes apart and I cleaned that connection.....still no horn. Any thoughts? Thanks..... Don
