Hello,

I have a pair of K-Line Alco's.  

One is a powered A and one is a non-powered A.

They both light up, but there are no sounds and no movement.

There is a switch underneath that I figure is to lock in the forward position.

I tried the switch in both positions with the same results.

I tried just the powered A unit on the track with the same results.

The wheels do move freely.

I am using TMCC if that matters.

I cannot find a manual anywhere online.

Does anyone have a suggestion to make these run?

Thanks for looking, Ron.

That switch is to lock it in the last  position, not just forward.

If you are using a CAB-1 & PM-1, you need to be sure the stall voltage is set to zero, or that diesel won't change direction, but with the reversing switch "on", it should default to forward in about 20 seconds.

Depending on the year, there may be two switches on the bottom of the diesel, one for the reverse, & one for series/parallel. Check to be sure you are moving the reverse switch.

Not sure what you mean by making sure the stall voltage is set to zero.  Several other locomotives are working fine.
