In lieu of a meter, you might try the following: Let the rig run for
several hours, or a day, and see if the power cycles on
and off without the delay. If it is normal, lightly freeze spray areas of
the power supply while cycling power until the delay
reoccurs. Then localize the spraying to individual caps, until you find the
culprit(s). Sometimes requires heating the area back up with a blow dryer.
Use to be the 'poor-man's' troubleshooting procedure, but not so much
today, considering the prices I'm seeing for freeze spray -hi.
