I appreciate the responses. I also get an Error 10, which must mean no read on Service Track. I tired both. When I disconnected the feeder lines from the controller and touched them to the wheels, they turned, although only a little. I also tried the pull connectors on top and got a clicking sound. Not sure what all that means, but the signs look like I need a new decoder. That's too bad, since I never really got my monies worth out of this item.
