[T3] horn internals


<x-flowed> I'm surprised this hasn't happened sooner, but after hanging under the bumper for 40 years, the horn finaly died. It had power and with a good ground still no-go. When tested with MM had a very high resistance circuit across terminals. I opened it up to find some moisture, and a small amount of corrosion/crud between the two metal strips. Now I've got a good circuit, drawing 3A at 6V, but no noise. Any ideas? This is such a simple circuit, but I really don't understand what creates the vibration/oscilation. The crud was on what I believe is the "hammer" tip. I'm sure I can get another horn, but now I'm curious how it works.
