It's quite simple really. Simply fit the car with metal wheels that have metal axles. The wheels will have the axle going directly into a wheel on one end and the other end will have an insulator where the axle meets the wheel. Install the wheels for the front truck so that the non-insulated wheels are on the right side. Now, install the wheels of the rear truck so that the non-insulated wheels are on the left side. Drill two small holes in the bottom of the car, one just back of each truck on the centerline of the car. Strip the end of a thin wire (22 gauge or thinner) about 2 1/2 inches back. run the wire down through one of the holes and wrap the stripped end around around the axles of that truck. Do the same with the other truck. Now run the wires from the car (in whatever fashion you choose) to the loco (again in whatever fashion you choose. I just drill a hole to run the wires through.) Attach the wire from the front truck to the right side feed wire in the loco. Likewise with the wire from the rear truck to the left feed wire of the loco. This should take care of your problem.kase said:can some 1 help me install metal wheels on the car coupled to the loco and run wires from the cars axles to the motor in the loco
