I have had this phone for a little while now. It dials out and receives calls but will not ring. All 4 wires are going to the right terminals. When I got the phone I had to do some reconfiguring with the wires to the network in order to make it work in doing that while also attempting to get the ringer to work the gong would move when touched to a certain terminal but that was it. There is a grey wire coming out of the line switch that does not go to anything it just has a yellow piece of tubular plastic around the end of the wire

Are you saying that it just stopped ringing or did it ever work properly?

The ringer leads should be connected as follows:

Black: Terminal L1
Red: Terminal L2
Slate: Terminal K
Slate/red: Terminal A

The spare switch hook lead you mentioned that is insulated and stored is fine. That's how it should be.

There are several things that can go wrong:

1. The ringer coil is bad;
2. The capacitor between terminals A and K is bad;
3. Improper wiring;
4. Low ringing voltage/improper frequency. This is happening a lot these days due to telephone companies using pair gain equipment.

The ringer has never worked properly. How do you go about testing the ringer coil and the capacitor. As for the wiring coming in from the line the yellow goes to G black is going to L1 Green is going to A and red is going to F

Well, in a way this is good news. Those components rarely fail. Disregard the yellow or black line cord connections as they are not involved with the ringer. You have a "-MM" model set, but I assumed that you had the "-DM" model.

I can't seem to locate my wiring diagrams for the -MM set, so let me just try this instead:

Red ringer lead goes to the same terminal with the red line cord lead;

Black ringer lead goes to the same terminal with the green line cord lead;

Slate ringer lead goes to network terminal K;

Slate/red ringer lead goes to network terminal A.

I put the black wire with the green one and the red with the red. The ringer taps now when the receiver hook is picked up and the phone will dial out but it will not cut off the call when the hook is back down and if just connected to the line and not being use it makes the line go dead. Should both the black and slate red wires from the riger be together on terminal A with the incoming green line?

I just did the coil and capacitor test it did not short out the phone but when you dial a number and then put the hook down to hang up the phone does not hang up. Does this mean that it has a bad coil?

You may have a bad capacitor. Remove one of the ringer wires from either terminal A or K and see if the line releases when you hang up.

I got the phone working a while back. There was a sticker giving the year and the model on the bottom of the phone I peeled the sticker off and it listed the phone as a model 2500DM so I looked up the schematic for it and wired it according to the diagram and it worked. Thank you for all your help

Glad to hear it all worked out. Thanks for letting us know.
