It looks like the + leg of the capacitor runs through the pcb and makes contact with the test spot under the capacitor. I think I can just solder a test lead to the + leg of the cap.

You mentioned you started with 100k ohms for the memory.
Here you said:

"the mem works in the same manner... 50k ohm works."

I start with 100k for the memory right?
or
Is it safe to start with 50k ohms for the memory?


I'll post my results and the values I end up using for fixed resistors. at my own risk!!
