convert hardwired phone to modular

convert hardwired phone to modular

(OP)
I have an old rotary hardwired phone that I want to convert to modular RJ11.  I stripped a base cord out and have the red and green wires to carry voice - that works ok.  I cannot get the ringer to work.  I get dial tone, can call out, and can even receive calls, as long as I "know" someone is calling.  I just cant get the bells to ring. Is this a grounding issue? I've tried the yellow wire, black wire and both, but still can't get it right.  Anybody have any ideas?

I'm posting this in the cabling forum as well, just to cover the bases.

RE: convert hardwired phone to modular

ON THE RINGER THERE SHOULD BE 4 WIRES BLK, RED, SLATE, AND RED/SLATE. ON THE NETWORK OF THE PHONE YOU WILL FIND L1-L2-A-K THE RED GREEN GOES ON L1 AND L2 ALONG WITH THE RED AND THE BLACK OF THE RINGER THE OTHER 2 LEADS FROM THE RINGER GO ON THE A AND K POSTS. HOPE THAT HELPS

I think you will find your answer in the Cabling Forum. Open up the phone and move the ringer wire that is connected to the yellow line cord wire to the terminal that the green line cord wire is on.

RE: convert hardwired phone to modular

Old phones are polarity sensitive on the tip and ring.  Try swapping the red and green

RE: convert hardwired phone to modular

Ringers are AC devices - the polarity switches 20 times per second; polarity doesn't matter here. Old touch tone pads ARE polarity sensitive, you can install a bridge rectifier in line with them to combat that problem as well.

Moved the Red ringer lead to the lead with the Green line wire and it worked!  Thanks for all the help - thanks TTT!
