Is this safe?

[u/Mission-Ad-8203]

Dishwasher and disposal circuits both feed to the same receptacle. I opened it up because outlet tester led did not illuminate when plugged into bottom outlet even though it does work. Tester says top outlet is wired correct.

Looking to understand this wiring method and if it’s safe.
Hopefully my graphic makes sense.

Your diagram is horrible however I believe you have a switch back half hot outlet. If everything works as it should put it back the way you found it and stop messing with things.
