GPO Dial No 12 wiring advice needed - UK Vintage Radio Repair and Restoration Discussion Forum

oldyard · 6th Jul 2014, 1:13 am

I have recently obtained an old 232 GPO phone with a No 12 dial.

It has in the past been restored, but I suspect the dial has been incorrectly wired up. (as in I've tried it and there is a problem which I think can be traced to the dial connections)

I have the N322 wiring diagram

and the dial matches the illustration at

But could somebody confirm the numbering of the terminals as shown in the fig3 picture on britishtelephones

Thanks in advance

Thanks 198KHz
(Sorry for delay in thanking you - unexpected trip and now catching up)

It is the 3 and 4 terminal that I think are mixed up, is terminal 3 the slightly higher post to the right in the picture?

Sorry for delay also - went away on 10/7 and returned yesterday.

Aye, terminal 3 is the slightly higher one on the right.
