Phone doesn't ring

[John47]

My main phone has given up ringing. After a lot of trying different things
the consensus view is that there is a break in the (pin 3) ring line somewhere
in the circuitry, but the BT master socket is fine.

I read on the web that
"OK - so you have tested the cables and there is 150 yds of cable
buried in the newly decorated wall and only 2 wires have continuity -
what do I do??

This is about the only occasion where you cheat and use a second
master socket. Ideally you use one designed for PABX use but beggars
can't be choosers, it's normally 19:30 and mother in law is due to
arrive in twenty minutes. Nip down to your local DIY shed and buy a
MASTER socket.

The second master gives you back your ring signal so connect the two
working wires to terminals 2 and 5 on the new master and hope for the
best"

So I came to the Solwise web site and was excited to see that I could
buy a Ring Capacitor with the description
"A BT slave socket can be converted to a PBX master type by the
addition of a 1.5 uF Bipolar Capacitor between pins 2 and 3 of the BT
socket."

You sent a Ring Capacitor 2.2 uF 63V Bi Polar Ring Capacitor.

I don't know whether the difference in capacitance is significant or
not. I attached it to pins 2 and 3 with the result that there is no
dial tone - just a low level buzzing.

I changed it to pins 5 and 3 which restored the dial tone but did not
enable the phone to ring. (I then removed it)

So I am slightly lost - did you send the wrong capacitor or is my
circuitry up the spout or should I go get a secondary master socket?

So you removed the existing incoming wire from pin 3 in the the remote socket? Yes? Then put the capacitor across pins 2 and 3 in the socket? Yes? Well that's correct.... Have you tried another phone?

As Steve says 'the existing incoming wire from pin 3 in the the remote socket' is the route of the grief IMHO.
Have you removed it?
