Thanks, again, Jim! I greatly appreciate your help.
Where and how would I place a jumper to turn the PSU ON? The Power Switch?
I'll try the tests again and be sure to make metal-to-metal contact with the
Multimeter.
Are you suggesting that I probe the female socket on the power cord with the
Multimeter set on 120 volts DC while the power cord is plugged into the wall
socket?
The settings on the dial for this Multimeter are limited to 15 volts, 150
volts, and 500 volts. The same holds true for AC voltage settings on the
Multimeter dial.

With kindest regards
