Question Split receptacle

I have a split receptacle controlled by a single pole end of run switch. The half that is constant hot works O.K. The switched half is not working.
The outlet has a black, red, shared white neutral and bare ground. If it matters this is an isolated ground recept. The tab on the outlet is broken off.
Voltmeter shows 35V at the red wire and 120V at the black.

Switch which has a black and a white wire checks O.K. for continuity. In the off position sw shows the same 35V at the black wire. In the on position I have 120V at the white wire.

I don't know if this outlet ever did work correctly. Outlet and switch have both been replaced. Why would I be getting 35 V???? What am I missing? Everything else works O.K. Please help.

P.S. This site is great!!!!!!!!!!!

Put your digital voltmeter away and do not use it again on electrical wiring. It is just about useless. You are reading phantom voltage on the wires. For electrical circuits and wiring you need an analog meter.

The red wire at the receptacle is open. It is not connected to anything.

You need to find where the red wire comes from. Based on your description, it is not at the switch. There must be another receptacle where the switch loop originates from. At one of the receptacles there will be a white wire connected to the hot black wire. The black wire from the same cable as that white wire must connect to the red wire that eventually gets to your receptacle. Check every receptacle in the room. The red wire may very well travel through all of them.
