Reply to "Wiring American Flyer K325"

Thanks Tom. I have used quite a bit of 'tuner cleaner" on the reversing unit but will inspect it closer. The original tether wiring was badly decomposed and I substituted black flexible wire in a tube of heat shrink to keep it neat.  I haven't bothered connecting the 5th wire yet as I knew what it was for and wanted to get the motor running. I've attached a picture of the wiring diagram I found online. I used the center diagram..
