Replaced Outlet and Switch, Now Light Won't Turn Off
Looking at the 3 way switch in the photo, the black is the hot (common terminal) on the switch and the white and red are the traveler wires between both switches. And on the diagram for the junction box,15 and 11 looks like the two 3 way switches controlling the outlets on the red wire (switched) and the black feeds the hot side (hot all the time).
These receptacle outlets look like their split controlled (one half hot BLACK and one half switched RED). The taps in the junction box (separate of course) has all the blacks HOTS and whites NEUTRALS and red SWITCHED wires feeding the rec outlets. Hope this helps.
