Hi, I am new to this forum. I am restoring my childhood American Flyer train. I’ve cleaned it up, replaced the finger things on the control unit and the train runs ok. The problem is that the control unit coil gets very warm. I can keep the motor running continuosly at 6-7 VDC, but when I increase to 12 VDC,the coil gets very hot. Any ideas how I can remedy this?
