Try pulling the reader plug from the back of the
call control unit (it's
one of 6,7,8, the other 2 being the keyboard and the distributor disk,
trace the cable to find which is which). IF there;s a short in the
reader, that would elminate it.
The reader unit plugs into a module that was installed inside the stand.
No. (Well, it does, but that's not what I meant).
There's a cable harness that attached to the reader. It splits into 3
sections. One goes down to the stand and plugs into that module you've
found. This is the power supply for the solenoid in the reader itself.
One little branch connects to the leaf contact switch on top of the
transmiter shafter in the typing unit. And the 3rd branch plugs into the
back of the call control unit. It's that last one I want you to unplug.
At least, that's how an ASR33 is wired. If this is a 32, I assume it's
similar.
