I measured at the cable. I acted like there is a R/C
network across the
relay,
that is the reading went up over several seconds to just under 200 ohms.
It
appears that there may not be just a simple relay.
Hmm. I am going by "Figure 5-7 Teletype Connections", which led me to
expect Relay+ to be connected to the relay, and to the cathode of a diode.
I expected Relay- to be connected to the anode, and also to a resistor,
which connects to the other side of the relay. It shows a capacitor across
the relay contacts, which also connect to the local switch and the reader
solenoid.
I don't suppose I could prevail upon you to trace the connections/schematic
for me?
Thanks!
