Well a friend of mine sent me his PS 3 diesel engine that works fine on his layout after my problems with the used steam engine I bought and low a behold it does not make it around my layout ( when my 4 PS 2 engines do) as it goes a long the engine number on my DCS commander display start to flash and I have no control over the engine. When I run the PS2 engines inch by inch I never get the flashing number nor do I lose control ever. I have cleaned the rails, pickups and wheels and got no improvement. I have also checked all ground connections. It's like the PS 3 engines need more of an output from the commander. I also have a small volt meter that I attached to a set of trucks that when I wheel it around the layout it never drops more the a tenth of volt. Look for any advice help I can get.
Thanks
Bob
