Lionel 022 reverse loop wiring

022 switches have the derail feature built in. No special wiring is needed. Just make sure you have the two insulator pins in the correct rails. 

So just track voltage?  I have some test pieces put together with the insulator pins in the correct position. I’m metering 18v on the track but the controller lamp doesn’t light and the switch controller won’t move the switch. I also test the engine going through the return side of the switch but it still doesn’t make.  Again, I’m brand new at this so it’s probably something simple.  I’ve tried to find YouTube videos but can’t seem to find videos on basic wiring/setup.

Take the cover off the switch machine.  There is a pin where one can apply aux voltage.  This metal pin is where one can connect a "fixed voltage plug".  When the plug is not being used there is a piece of metal that bends and touches the pin applying track power to the switch.  When the fixed voltage plug is in it disconnects this piece of metal from the pin.   Sometimes this is bent so that it is not touching the pin when the plug is not in, preventing track power from powering the switch.

I was able to set up a test track with both switches and both loops.  I discovered that both metal pieces for the fixed voltage were bent and not making contact.  I put a wedge in each one so that they would make contact and both are now working.  Thanks for the help!  That would’ve taken me a while to figure out, especially with both having the same problem.
