loco harness

Does it stop at roughly the same place all the time?

  It will stop at random places. This loco belongs to a friend. I took it on because I have the very same one that had the same drop out problem a couple years ago. I cured it by replacing the harness. I am not comfortable trying to redo the small solder joints.

You need to use the universal harness and solder to existing harness to  replace the tether.  Otherwise it is a custom harness build and you need some experience with this to make sure you wire it correctly.  Can you post a picture.  G

Before you go further, why did it have past solder work?  Was this your friends engine from day one or a fleabay queen?  Myself, I would remove the locomotive body and tender body and do the following.   Plug the tender plug into the engine and do a continuity check on each wire from the board to it's final destination.  Chances are you you will end up loosing continuity somewhere on the ten pin by a cold solder joint.  This is not uncommon.  Secondly, I would closely examine the solder work done before and repair if needed.  

Never be to quick to throw parts at an engine until you have identified the situation that is causing your problem.  Anytime you are in doubt of your soldering skills, have someone look at it that can be of help.
