Default Re: Incorrect bell?

Regarding the bell, your descriction sounds like a DC trembler bell. Have you tried feeding it with a DC voltage between 6V and 12V independently of the rest of the circuitry?

Looking at your third image, I cannot see the wiring clearly. The blue wire of the bell appears to be connected (via the 5th terminal of the telephone) to the green(?) wire of the black cable that I take to be the line cord, and the yellow wire of the bell is connected to the yellow of the line cord (I assume the component at the bottom is just a connector block). If this is correct, how is the other end of the line cord wired? Also, to what, if anything, is the black wire of the line cord connected?

N.B. Tony posted while I was composing the above.
