The disc and mating surface inside the wheel were cleaned, the disc polished. The contact sleeve and plunger were installed, and the disc set in place. The plastic ring was inserted into the cup and placed on top of the disc. Care was taken to ensure each leg of plastic ring cleared the disc and contacted the wheel so as not to pin the disc against the hub. The screws where tightened only to the point of keeping all parts in place, allowing the cup to float, as described. At this point attempts were made to sound the horn, which were unsuccessful. The relay made no sound, either. This process was repeated three times.
To provide as much peripheral information as possible for accurate diagnosis, I thought back to the evening of the first attempt and recall the following: After resetting the wheel and returning all parts to their original locations, I did bounce the cup, as a test to see if proper function had been restored. The horn sounded. I lined up the horn button to complete the job. When pressing it into place the horn sounded again. However, after installation of the button, no function has been possible. The rest of the story you know.
A question: Regarding the disc (Belleville spring), what is the suggested free-standing height? I have attached a photo of mine. The inside height is about 1/8.” Might this need to be adjusted or replaced?
Unless there is a problem with one of the components, it sounds like I’ll be digging into the column next.
Thank you for your continued support,
Jim
