I agree. As a matter of course during decoder installation the wire from the frame to motor is disconnected. You can elect to use that wire as one of the power leads to the decoder or install brushes at the wheels and obtain power that way. My comments assumed severing of this direct connection, thus my confusion regarding electrical isolation of the motor from the frame.
The question in my mind is should the frame be electrically neutral in the DCC good practices manual? I use the frame lead wire to the decoder and have never had any problems.
