[GreenKeys] ASR33 reader

[John, W9DDD]

Welcome:

My recollection is that the reader has a cable to connect it to the 
distributor.  That goes through one of those several connectors on the 
back of the electrical service section.  Perhaps the connections in the 
plug have gotten oxidized over time?   Or perhaps you've already tested 
that continuity?  Do you have wiring diagrams?  Check Navy-Radio.com for 
a whole section on Teletype documents.

OK,  reviewing your post, I see you've already essentially done that?  
Perhaps I should leave the suggestions to those who have worked on one 
more recently than 1981?

I think this would apply to the 33 as it does to the 28, turning the 
motor by hand without power (I think you can pull just a motor fuse so 
you still have signal power.  Then as you turn the motor slowly you can 
watch as parts more.

Or using the slo mo feature of your cell phone camera some times is 
helpful.  I'm thinking perhaps the pins aren't moving quite far enough 
through the tape holes to make contact.

Enough speculation ... good luck with the hunt.  Hopefully someone will 
provide more helpful information.
