Hello All...

I've had a lot of expert, valuable help restoring my model 15 on GreenKeys.  Now that most things are settled, I still am experiencing a lack of communication from the keyboard to the teletype printer.I have checked the loop through the HM parallel magnets and keyboard using 120 VDC and 60 ma. current.The motor runs smoothly. The magnet engages when the loop supply is on. The shaft on the keyboard reacts properly when the typing keys are struck, BUT the printer doesn't print with the key strokes. What's missing? Thanks in advance for your help... Bob...
