Are you removing all telephones when you test?

I would seperate all telephones from all the jacks. I would then open a jack and use my voltmeter across the tip and ring, usually the green red and measure the co battery. It should -48 to -52 volts dc. Keeping your test leads across the tip ring set your meter to AC and have someone call into the telephone number assigned to the jack. You should see the digital numbers or bars rising or falling. I used to carry a cheap analog meter because it had a needle. When set to AC on incoming ring the needle would move back and forth along with the ring voltage. You should see it peak at 95 to 102 AC.

If the phone is old the ringer capacitor could be open, shorted or dried out. Are the ringers concentric? Sometimes people dont want the bell to clang and they turn the bells out which clears them from the clapper. On incoming ring look at the clapper is it moving back and forth but not making contact with the bell. If it is moving a little try moving the bias spring, connected to the clapper arm, to another position.

Well, it's been a month since I offered to send a ringer. No response as to where to send it. I'm done here.

If it's a 554, set the bias spring on the ringer to the low physical resistance position (there are two positions).
Make sure that the ringer is wired with one side of each winding to the line, and the other wires to the capacitor position on the network.
The easiest way to do this is to find a drawing of the phone and wire it according to the drawing (normal).

Electrically, you have a winding lead to tip, the other to9 ring and a .47 uf capacitor in the middle. The capacitor is inside of the network unit in a 500/554.

The FIOS boxes and ATA's aren't great with mechanical ringers as a rule.
