MTH SANTA FE ABA PROTO SOUND 3 PROBlem

Possible smoke fluid issue, but in the absence of any real information, I would be speculating as to the actual issue(s). I suspect a short because it is obvious that this should not occur. I would re check every single wheel and make sure everything is clean and neat. Then I would not use the smoke function/oil and see if this makes a difference. Further, if you have too, take the shell off the lead unit and see if anything is amiss. Sometimes things get loose or out of sorts and that can cause a short. The other units should be checked in this manner as well. If you are not sure about this, then do not remove the bodies of the locomotives. Instead, contact MTH directly and ask to speak to a service tech. Yes they are busy, but I have had such problems as well with previous MTH locomotives and the guys up there at MTH were very helpful at helping me to determine what was actually wrong.

If all else fails, it may become less expensive to invest in a really inexpensive set that you can depend on for now until the matter can be resolved. After all, one cannot be train-less......

Hope all works out for you. Pete

Check the powered trucks to see if a wire is sticking out where it has rubbed on the wheel flange like on my F7.
