Rotary 500 Can't Dial out

Besides the pulsing contacts what else could cause a rotary phone not to dial out?

I checked the pulsing contacts because that is what worked the last time. They are fine and I did hear them too when dialing but the dial tone stayed constant.

Background:
The phone did not have a wall wire, so I had to buy one on ebay and got a dial tone to work.
It didn't ring because the red wire was taped by the dial. I put it with the right screw and it works.
I have a land line and other rotary phones have worked.

I'm stumped. Any help will be appreciated.

It is requested to post pictures in your posts, outside links will eventually go away and your post will be meaningless. Also a picture of the back of the dial would be helpful in diagnosing your problem.

Harry,

Thank you for letting me know. I'm trying to attach one but it won't go through.

Is there a size limit?

The network wiring, including the dial wires, appears to be correct.  We do need to see a pic of the back of the dial with the dust cover removed.  We can then view the dial contacts to see if something is not right there.

Thank you again for the response.  I shot a video of the back, and here is the screenshot.

If you disconnect the green dial wire from the RR terminal, so you still have dial tone?

The clear/white nylon cam is out of position (right side of gear train).  It is now at about a 12:30 position and needs to be reset to about 10:00 to close that contact with the dial at rest.   The easiest way is to remove the two screws holding the gear assembly and move the assembly back a bit to allow repositioning of that cam.  Then reassemble.

Edit -Found the thread with lots of details/pics on this subject:

And a pic from that thread showing correct cam position

Poplar, I removed the wire and the dial tone was lost.

RotarDad, I shot a video of the contacts. I posted it on youtube.

Let me know if that is still the case. I'm going to review the links you sent.

Thank you both!!

I now see your still shot was of the dial in motion.  The cam does indeed look correct when the dial is at rest, so that does not appear to to be the issue.  The cam should push that set of contacts closed at rest and create the pulses when the dial is turned (1 pulse for number 1, 2 for number 2, and so on). The other set of contacts should be open at rest due to the black pin on the large center gear opening that contact set.  Take a close look to see that they are operating correctly.  From my view of your video, they do appear to be working properly.  I don't see anything wrong.  Do you have another 500 dial you could swap to try to narrow down if the issue is the dial or elsewhere?

RotarDad, thank you for looking at the video.

It's late here in the east and I have an early day tomorrow. I do have another one I can try and report back tomorrow.

Thank you again!!

With the wire reconnected, if you manually open the pulsing contacts -- say, with a business card inserted between the contacts -- do you lose dial tone?

Also, you may want to disconnect one of the 2 white dial wires. This eliminates the mute (short) on the receiver, so that you can listen to what the dial is pulsing. (Sometimes, the pulsing contacts remain open when the dial is being turned clockwise, which disconnects the phone and returns to dial tone when the dial returns to resting position. When one white dial wire is disconnected, you can hear the dial tone going away during windup if the dial has this problem.)

I am sorry about the image link. Now I have a better idea on how to post photos without causing a problem.
