I have 2 of these, both quit ringing the bell.

The first one had a broken secondary wire, re soldering got it working.

The second (coil) was totally burned up. I found the specs for it, bought some 30 gauge enameled wire on Ebay for $9.00.
600 wraps later, proper resistance (7 to 8.3 ohms). It now works!
I didn't trust the used ones available.
I'm happy!

Make sure the train wheels are not stopped on the track trip with the transformer power on. These coils are not designed for continuous duty at 15v.

I have been using MRC AH101 transformers for many years to run conventional Gilbert layouts. They have a 10V fixed output, that is enough to work the bell danger signal and give a lot more margine against coil failure. The same thing can be done using the variable output of a spare Gilbert transformer. Try 12V first, then lower it to 10V if the accessory keeps working.
