Trying to locate the Bachmann EZ track turnout green extension wire. The one they sell on Amazon has the wrong connector to the turnout, but correct one to the remotes and it's $15, Thanks, Chuck

I'm 66 and just now getting into this, a lot of fun!  I have a Santa Fe engine that will go in reverse only.  I have both android cell and ipod with EZ App.  Did restarts, complete shutdowns, don't have a clue.  Could it be a defective motor. appreciate any help,  Thanks
