ATLD,

Thanks a bunch. I will check the voltage later today, after I clean all the old gunk out of the tube and get the SR sliding freely.

I understand the first test, but not the second. How do I tell if they each read ground when the switch is not engaged?

Is that simply the lack of any current?

Sorry about the dumb question, but I am willing to learn...
