C-NET 425B very sensitive to motion

[Partyline4]

I picked up a post divestiture AT&T Model 500 for free at a local recycling place.

The dial is 1968 W.E and turns like a beaut.

The only problem with the phone is that it is very, and I mean VERY  sensitive to motion.

I narrowed down the loose connection inside the network to be where the Green Dial wire connects to the network.

Even stranger, I hooked the dial up to another model 500 and it seemed to give a similar problem, no dial-tone!

Touching a section of the hook-switch paddles seemed to connect to the dial-tone. I could not see any problems with the paddles connecting or disconnecting.

The point where the dial green wire is on the network is a little loose like someone has messed with it at some time.

Any help appreciated.

*UPDATE*

Problem has been located in HANDSET.

Either receiver or transmitter.

Is the green dial wire on RR and the blue dial wire on F?

Since you apparently have 2 problems (the dial and the network), it may be best to isolate them one at a time. You can temporarily disconnect the dial (write down where the wires go first), then move the other wire that is on F to RR. Now you can troubleshoot the network problem.

There should be continuity between the green and blue dial contacts, except when they open during dialing (they open and close 6 times if you dial a 6, for example). If you take the plastic back off the dial, you can see whether the contacts are touching while the dial is at rest.
