I am new to forums and train repair. I am seeking information on the Marx 666, specifically the correct Ohm readings on the field coil, armature and E-Unit, so I can diagnose and attempt repair of the motor.
Last year I replaced a broken reduction gear, but when the holidays rolled around we found that the engine was drawing too much current from the transformer and won’t run. A 12v battery jumpered directly to the armature and field coils makes the motor spin, but the field windings get very hot very fast. I suspect I may need to rewind some of the motor’s coils.
Any advice appreciated, including where is the proper forum.
