OP here again

I was going to start a new thread since the info below is a new wrinkle
but decided to post here with something I found on the ACE HARDWARE
site while trying to do some research on the 3 lights that I mentioned
previously giving me a BRIGHT YELLOW lite and a DIM RED AND CLEAR lites
- all three lit at one time.

I found this instruction as I said on the ACE site in an FAQ on HOW TO
use the CIRCUIT ANALYZER with the 3 lites

" What is the easiest way to test an outlet?

Use a receptacle analyzer. Leave the power on, but make sure nothing is
plugged into any outlet on the circuit, and turn off all switches on
the circuit. Now, plug the analyzer into the outlet. A series of lights
will tell you if the outlet is wired correctly and working."

I know of no one that does this or ever did this when using the tester.

If it is that important, I think it should be put into the instructions
with the tester.

Does that instruction make any sense ?
Might this be my problem vs something more serious ?

TIA again
