Greetings, I have been following your posts since I got more or less the same trouble as Larry had. You see, I have the same engine, It was bought used but running well in conventional mode including the RailSound, I knew this from the beginning. When attempting running it in Command Mode it was possible to addressed it with the ID number and get some responses such as light on / off, increase RPM, decrease RPM. However when it came to move forward or reverse it did it erratically i mean with intermittent action. I made then a test on separated isolated loop wit the Base1L attached to it on the U post and the outer rail at the lockon device same outcome with short circuit protection.
I recently bought a new LCRU1 as following your posts and change it yesterday, but again, I got the same performance . Nevertheless I after replacing the LCRU1 and testing it, the sounds when on for a little while at starting the engine and then went off and work no more. Now that I have the schematics thnaks to you guys, I will review it all and check my the wiring connections. Then would come to you back for help or the share my experience anyway as Larry did.
I can tell also bought RD Teal Book "Modern Toy Trains Repair and Maintenance " and using it as a guide. There I learned that pick up contact rollers are frequently overlooked and can make the difference in performance between command and conventional running modes.
I´d appreciate it very much any bit of advice, I´ll come back soon with my progress on this issue.
Many thanks
ARTURO
