Sorry to bring up such an old thread, but I am having the same problem with the same type set up.
I have a WE 500 and the ringer coil only has 2 wires. Red and Black. Also with the 425E network.
I followed hbiss advice

Ok, try this. Red to "A" and black to "F". Now jumper "K" to "L2".

Seen here.
Yet the ringer still does not work.
Here is a photo of the coil.
I notice mine has the black thing on it (with the numbers and letters P8292ZN19) yet any photo I see of other ringer coils does not have this.
Any help would be appreciated.
Thank You
