AC input wiring

Just to verify that the problem is not in your cab wiring, have you measured the voltage on the wall outlets with your arcade cab unplugged?

I just wanted to add that I would do this the very first thing before I go pulling down ceiling light fixtures.
Make sure the problem you are seeing is in the house wiring and not your cab wiring before doing a lot (and it can turn into a whole lot) of work.
If it is in your house wiring, you may want to get a licensed electrician to check into it, someone you know is good.

Thanks for the info.
In my basement I have 4 outlets that were installed by an electrician a few years ago. They are on their own circuit and they are not switched. I took some measurements on my setup using one of them while everything else on the circuit was unplugged. Inside the outlet box I read 118v hot-neutral, 118v hot-ground, ~0 neutral-ground and the receptacle tester checked out OK. I plugged in my test setup and took the same measurements with the switch on, results were similar: 119v hot-neutral, 119v hot-ground, ~0 neutral-ground. With the switch off I read 15.86v hot-neutral, 15.86v hot-ground, ~0 neutral-ground.
I will try turning off the breakers one by one later and see if that makes a difference.

Looks to me like the problem is in your test rig. Maybe the switch is bleeding through, or some of that romex cable you are using.
15.8 volts on a digital multimeter is probably not bad, and will probably drop to zero if you plug your circuit tester into your test rig outlet, with your switch turned off.

I see your outlet and the light switch and they look to be wired OK but what is the little rectangular item with black wires coming out of it in series with your hot line?

I believe that's just a terminal strip. (plug the wire in, tighten the screw)
DaOld Man - You are thinking along the same lines as me, but you sure put it in better terminology.

Turn the breaker off to those 4 outlets and take measurements the same way you have been doing on your test rig and see if they show the same voltage you are concerned with that shows up on your rig.
Essentially you have two identical setups..... the house, having a breaker as a "switch".
So thoroughly test THAT first.
If you get the same results there, then obviously so will your test rig.
Your rig/switch wiring looks fine to me.
For testing purposes ..... disconnect the ground wire on your rig and then test for voltage when the switch is off.
