About this isolating thingy

That's incorrect. All you need to do is isolate both motor connections from the frame. That's ALL. As long as there's no electrical continuity between the motor brushes, and the frame of the loco, you're good to go. <br /> <br />[quote]QUOTE: <i>Originally posted by cacole</i> <br /><br />Touch one lead to the frame and the other to both brushes, one at a time. If you get a tone or Ohm reading of anything but Infinity, the motor is not properly isolated from the frame. Just putting electrical tape between the motor and frame is not enough -- you must also change the machine bolt that holds the motor from a metal to a nylon one; or use double-sided white foam tape to secure the motor if it is flat enough for the tape to keep the motor from moving under load. <br /> <br /> <br />[/quote]
