Thank you both for your helpful responses. I have a bus line, shoot power to both sides of the layout. I disconnected to take it out of the picture. I separated the layout into about six sections, taking the track apart. I went around with a small transformer and a clip on and connected each section independently. Each section tested fine. I first turned up the transformer. The red light did not come on. I than placed a caboose with a light. It was fine for each section. Now I’m thinking that somehow the bus line is bad or hooked up wrong. Before I did anything else I reconnected the six sections back to one. Instead of hooking the track back to the bus line, I connected the small transformer, using the clip on, to the track. What the ****...... the red light comes back on. So divided we are fine, together it fails. Any thoughts?
Thank you again. Fred O.
