A few months ago, I purchased a Lionel 6-11411 TMCC L-2a Mohawk, and I just recieved a Lionel LEGACY command set #990. I set up the system (following the instructions, of course...) and move the locomotive. All of a sudden, the locomotive starts acting strange and starts to play random sounds. The whistle wouldn't stop, and the crew talk wouldn't stop glitching, replaying over and over. Is this an issue with the locomotive or the way I set up the LEGACY set? Because I just set it up, put the loco on the tracks, entered the settings in the INFO section and then ran it. Please note that I have 0 experience in LEGACY control, and I don't have a TMCC remote or a base. Any help will be much appreciated, thanks.
Did you program the locomotive as a TMCC locomotive in the INFO section? Press the INFO button and scroll over to the locomotive type and select TMCC, then press INFO again. See if that helps.
Yes, I did, and still nothing.
It may actually be broken. One issue that can cause random sounds is the drawbar either not being aligned or one of the wires broken under the heatshrink and making intermittent contact.
Do other TMCC and/or Legacy locomotives work with the Legacy command system?
