I got this ringer today. It looks similar to a C4A except that it has two wires instead of four.
Could this ringer be used in a phone that normally uses a four wire ringer? If so, how?
C4A:
Lead: Terminal:
Black L1 (formerly G)
Red L2
Slate-Red A
Slate K
C4C:
Black L1
Red K
Connect a strap between L2 and A

For details, make a quick trip to the TCI Library and use the Google site search for "C4A Ringer."
You'll get quite a few references, including 502-521-402-i5-service-500c-d-500dm-telephone-sets, which includes wiring diagrams.
