Ok, I am at it again...
 
Powering up the "really nice" ASR-33 that I pickjed up last weekend. After
checking thing out [voltages mechanical inspection, etc] I have powered it
up.
[F4 the fuse for the motor WAS blown, a replacement of the ssame rating is
holding].
 
Motor spins up nicely (real quiet and sweet!), with the mode set to local,
the break and here-is keys do the "right things", however NONE of the other
keys do. My first thought was an issue with the keyboard unit, but a swap
from my other (dirty, smashed case, etc) unit yields the same results. My
next thought was the distributor [since checking the schematic shows that
the break key does NOT require the distributor connectivty]....
 
Powered down, disassembled to look at the brushes, they look brand new [cant
wait till I get to post some pictures of this baby!!!!].
 
Every thing also seems to buzz out as I would expect.
 
This indicates that the failure mode might well (once again) be me......
 
Hopefully someone here will think of something I am missing.....
 
A reply e-mail would be appreciated, a call bfrom anyone with an idea and a
few minutes would be great! [If it is long distance, I can call anyone
willing to help].
 
My weekend will be some mich better if I get this working and buttoned up
tonight [It's so cleen that it is even scheduled to go in the living space
rather than my lab when buttoned up and working!
 
Thanks in advance.
