OK... I know I am not crazy, wish to see if others have any ideas about this. I installed ERR DC Commander and Rail Sounds Commander in a MTH 20-2151LP St. Fe F3 ABA set in 2015. The Commander is R4LC and the RS are of the latest ERR design for the time. Now for the enigma. I have ran this F3 ABA many times with a Cab1, pull pass consists of over 12 cars being 18" to 21" extruded aluminum with no problem. Today, while pulling only 6 alum 21" cars, the sound began being garbled when pressing the horn button on the Cab1. Thought it was possibly the Cab1, so I switched to another Cab1, with same result. Disconnect the cars and ran engines separate. Now, the engines had no response to the TMCC signal. When powering up the track with Cab1, lights come on and engines began to move, but weak RS. Again, shut down and after 30 sec. or so, power up. Now, have RS but engine responds as if in conventional. Then...… I hear a "clank" and the RS begins to fade out slowly. WHAT? There is NO PS1 in this engine, was taken totally out in 2015 when converted. Also, now, the engine consist ABA have forward, neutral, reverse, neutral, forward, etc...….. BUT, the powered A unit has ERR TMCC and RS in it...….. And, as you know, ERR TMCC does not have neutral sequence, only Forward to reverse, etc. I know this is weird, and I still hear a "clank" just before the RS begins to fade out. So.... move program/run switch to program and reset the engine ID and use feature code #6. Put back on track, single unit, and power up. Same as before with engine response to Cab1, but have no RS. Try reset ID and feature again, several times, and still have no RS. Removed shell and inspected, all is in good order and all connections good, even tested for continuity between connections of plugs. I am out of ideas, and am at complete loss about "clank" and neutral activity, even though it did this for approx. 30 minutes before I tried the ID and feature resets. Any suggestions?????
