Proper DecoTel Chestphone 881C101 Wiring
« on: August 07, 2017, 10:44:21 PM »
I'm trying to find the correct wiring diagram for a DecoTel chestphone 881C101. The closest I can find is this one:

http://www.telephonecollectors.info/index.php/browse/wiring-diagrams/doc_view/2348-88x-and-288x-design-line-telephones-881c109-tl

My phone works for incoming and outgoing calls, but does not ring. I've traced the wiring for the line and ringer wires, and they do match this diagram. I'd like to make sure the problem isn't wiring before I move on to capacitors and such.

Thoughts?

Thank you.

Search for 503-200-107 in TCI Library. The 881C101 is shown in Fig. 17.

Line connection:
Green to L1
Red to A.

Ringer connections:
Black to L1
Red to K

Thanks, that document is better than the one I found. The line and ringer are already wired as you suggest, so I'll try a replacement capacitor between K&A next.
