Hi folks,I have a (China Made) N scale Con Cor 4-6-4 Hudson. I am installing a Tsunami Sound DCC decoder in it. How do I go about insulating the motor from the frame. The motor wires are soldered to copper strips that appear to be riveted to the brush holder and bent to pass through the frame where they are attached to the wire. It would appear this is where they touch the frame. I read the install info from North Raleigh but they used an earlier model and replacement motor. Any experienced suggestions will be greatly appreciated. Thank you.confused: Harold
