it sounds like it's having a signal gathering issue but it's hard to tell exactly yet with what I've read. Sometimes a wire will get chaffed rubbing on the frame and that can cause issues. There's many things that can go wrong and it's always hard to tell when it's not in your hands.
Seems like so far, it has the not resetting, not answering to turning the bell off, anything else you can tell us?
Make sure when you try and add it, that there's nothing else on the track.
Use your good engine to do a signal strength test and tell us what it gets.
