I was given and old Tyco kit by a friend. I have it painted and built. I am having an electrical problem. It picks up power from on one rail in the loco and then a feeder wire goes to the tender for ground. It runs great in reverse, starts out with little power applied(no problems). When going forward you can hear the tender shorting out and I have to put the throttle at about 40 to 50 to get it moving. I have an MRC Tech 4 220 and a Tech 2 2400. I now have the unit dissasembled and cleaned out the tender wheel slots and cleaned the ends of the needle points on the wheelsets. When I built the kit I used "Blacken It" to blacken the brass wheels. The chemical actually made the axles unable to pick up power although I know that it should still work even after the blackening. I tested this with a volt-meter and had no continuity. Any advice would be helpful. If you know a way to rewire the train, that would be good also. I'm not afraid of a soldering iron. Thanks, Terry M. P.S. Did I make any sense?
