I have a large Super O layout with 42 Super O switches that work well. I’m expanding my layout.
I have recently bought 2 more SC 2s that only throw to straight, but not curve. When I throw to straight, I can hear the click. No click when I throw to curve.
I have six of these units working on my layout properly.
I have wired these 2 same as the ones working on my layout.
Does anyone know if these SC 2s can be fixed? Or how I can get them to work?

Make sure they are set up for switches only. Sounds like you have a switch set up on accessory mode.
I have programmed the units for switches with the TMCC hand held controller. I used “sw 1 - set”. Then moved switch setting to “run”.
Am I missing a programming procedure?
Don’t forget to clear the accessories first.
SC2 to prog, press ACC, press 0 for no accessories, press set.
Now program to switches as you have done.
I followed your directions to clear acc. programming. Then programmed to sw-1, set.
Still not throwing to curve.
Have you tried a different SC2? Maybe you have a bum relay circuit in that one.
Yes - I have tried another SC - 2. It works.
can the relay circuit be repaired or replaced?
I suppose, I haven't actually looked to see if the parts are available. Also, it could be the relay driver and not the actual relay. Again, this would be something that would have to be diagnosed.
Have you switched wires at "Thru" & "Out" to confirm it is the SC-2 & not the switch?
