1955 Rose Beige Making MMMMMMM sound

One dial wire (blue) needs to be on F, along with the hookswitch wire. The other dial wire (green) needs to be on RR. The dial shorts F and RR together except when the DP contacts open up when dialing.

Ben, may I suggest that you take a known working dial (from a working 500)--not just the contacts--and try connecting that. Otherwise, you are trying to troubleshoot 2 problems at once: the dial itself and the wiring. As my 7th grade teacher always said: "Process of Elimination."

Okay, thanks for getting the wiring in order. I hear the pulsing but no dial tone.

I will try putting on a different dial, though I am unsure if a 9 type dial would work on this one.

Thanks you,
Ben

7C, 7D, 9C, 9CA, 9CAM===all of these have the same connections. The later dials have two blue wires instead of one blue and one green, but still connect to F and RR.

Maybe Dennis can confirm it, but I think the nylon cam lobe is pointing in the wrong direction (if the dial is at rest).

Moving the slate/white wire to RR was only temporary to see if you could get dial-tone so move it back to F.

The green and blue wires from the dial pulsing contacts should be on F and RR but not both on RR.
This is shown in the pdf that I attached in my earlier response.

Did you move the hookswitch wire back to F?

Which hook switch wire? The yellow one?

Right now,

Blue and green dial wires on F

Yellow HS wire on RR.

Here is a color-coded schematic showing the dial connections.

Okay!

This saga is finished. I guess we were on some sort of wild goose chase, but southernphoneman noticed how the plastic ovel piece from the cam was bakwords. It's now flipped over and works great!

Thank you!!
Ben

I didn't know you could just pop off the cam.
