1.  Measure and record the resistance across the following pins on the PCB1BWKEY Plug-in Base (with the EDCO PC642C / ASCO 175 module plugged into the base and all wires disconnected):
> 2-3, 4-5, 6-7, 8-9
2.  If resistance is less than 8 ohms on the EDCO PC642C / ASCO 175 module is good
If resistance is greater than 8 ohms the  EDCO PC642C / ASCO 175 module is bad and should be replaced.
