Per AC Gilbert :
step 3) Reverse Unit Most locos have a reverse unit in the tender. Take the shell off the tender and spray a little tv tuner contact cleaner on the drum and fingers. Often power does not get to the motor because the contacts are not contacting the drum due to dirt and corrosion. TV tuner contact cleaner is sold at Radio Shack and lots of other places. It comes in a spray can with a little red plastic tube that you stick into the button to aim cleaner at precise spots. If the drum of the reverse unit is very dirty, you may want to clean it. To do this, unscrew the screws holding the reverse unit to the tender floor, turn the reverse unit upside down, and clean the drum with q-tips and contac t cleaner. click to see more

A) Never apply power to a questionable motor for more than a few seconds at a time.
B) Always test locomotive by itself without other cars attached.
C) Use minimum voltage (8-10 volts)
