I am attempting to service my 1960s Lionel 2615 0-4-0 engine's motor. It has been disassembled, cleaned the wheels, roller pickups, reversing unit, motor brushes, polished the rotor, lubed gears and shaft,and reassembled, leaving off the shell to test operation before full assembly. It had troubles getting going at all
https://vimeo.com/196118230iuntil I gave it a bit of a nudge. Then it worked great in reverse but sputtered and stammered trying to go forwards. I wanted to shoot a video, so I stopped to set up the tripod. Now it does not even try to go in either direction, although I can see the reversing mechanism going up and down easily. See the attached video. I have tried moving the slide switch on top from position to position to no avail. It seems like it may be due to old wiring shorting out somewhere. Any suggestions?

Hold the locomotive upside down and try spinning the drive wheels by hand. They should turn with no binding.
Check the e-unit contact fingers that they are clean and making good contact with the drum. Make sure the drum is in good shape and has clean and shiny copper strips.
If you still have trouble, disconnect the e-unit completely and wire the motor per the attachment. The motor should run well in one direction. Reverse the brush connections to change the motor direction.
If the motor runs well, the problem is in the e-unit.
