Electrical – Funky Wiring for Half Hot Receptacle in Bedroom

electricalreceptaclewiring

I am in the process of upgrading switches and receptacles in an older home (DIYer). I love learning electrical, but I am stumped on the wiring for a circuit with a half hot outlet. Wondering if a kind soul might be able to point me in the right direction.

Basically, I replaced old receptacles and switches with Decora units, connecting the wires the same way they were originally. I broke off the tab on the half hot outlet (Outlet A in the diagram).

There was one outlet that was a switched outlet.

After swapping everything out, the receptacle that was previously half hot does not operate as expected, and stays on all the time.

Any advice is greatly appreciated!

Simplest option is that outlet F was also half-hot/half-switched and you were not aware of that, so breaking its tab (or isolating that red wire from the outlet and insulating it, if you don't want it half-switched) might fix your problem.

I would guess that you missed that in the original wiring, or it would work as expected.

Connections at B look like a switch loop out to the switch C, and the switched hot on red. The white wire in the switch loop should be re-marked with red or black tape at both ends to indicate that it is hot.

Actually, the blue connections at B look like you've got another half-switched at B, as well.
