Motor Isolation

Andrew Bell said on the 29 July 2005 Subject: [DCC4EVERYONE] DCC Connections

A guy wrote in large letters "THE MOTOR MUST BE TOTALLY ISOLATED" This is partially correct. Most can motors have connections coming out the back or sides that are isolated from the motor casing, in this case the frame of the motor can be screwed down to the loco frame with no problems, and the grey and orange wires run to the isolated connectors.  On a lot of the older open frame motors one of the motor connections is often soldered to the motor frame, these are the problem units.  Often the connections can be unsoldered and set free from the frame but if this is not possible then the whole motor has to be isolated from the loco frame.  This is why can motors are so much

easier to work with when using DCC.
