I purchased a Lionmaster Challenger recently. I was putting it through its paces to see if there were problems, using TMCC. I have a CAB-1L Base and remote. The engine & tender worked fine, Sounds, Throttle, Forward, Reverse, all worked well. Then I tried the Boost. The engine took the command, but would not get out of boost mode. Ran off the track at first turn. No apparent damage. When I put it back on the track and tried it again, engine went into boost and would not release. Tried several times with same result. I tried to ENG 1, AUX1, 0 reset and this did not work. I then decided to reprogram the engine to factory defaults. I shut off track and base power, set my engine to PROG, turned the base back on, placed the engine back on track, brought up track power, then entered ENG 1, SET, ENG 1, AUX1, 7, 4. Train Engine whistle acknowledged both the 7 and the 4 command. The 74 code is specified in owners manual. I then put train back to RUN, and retried operations. Engine is still stuck in Boost Mode. I have another Lionmaster engine, and it works fine, so I don't think this is a power, base, or remote issue. Have researched this online and retired the reprogram several times. No change. What am I missing? Is there a potential problem with the engine?
