I have a old Max Gray Loco which uses an open frame motor. I use DCC for control and usually deal with can motors. However for this install I'd like to try using the original Open frame motor. I insulated the motor from the frame using nylon fasteners. But the motor shaft which goes into the metal gearbox obviously overrides my effort causing the frame and motor to become shorted. Not sure how to approach this issue. Your thoughts appreciated.
Thank you
Bob
