[Larry Tighe]

Thanks to all for the shunt relay and test functions.  I guess the shunt on 
the line proves continuity to the test bureau....too, I think "old" teletype 
(Morse code) loops were all in series and going off line would break the 
loop if not for a shunt.

The reason I'm probing all this is, I want to operate the 28's in as 
original condition as possible.  I don't want to "jigger" it but keep it 
factory original.

Again, many thanks to all...lots more questions to come :>)
