What would cause an engine to work perfect in all respects in Command mode, but not work in conventional? It's an older Lionel GP9 from 1997. As soon as power is applied with the transformer set to conventional mode the lights come on in the engine but no matter how long I wait it will apparently not recognize that there is no command signal. I thought it was supposed to wait a second or two while it checked for a command signal and then the light comes on to indicate it is ready in conventional mode. But it just sits there forever - with the lights on no matter what activation button is pressed on the transformer. It's a 6-18567.
All I ever seem to do is ask for help. It's getting embarrassing.
