Reply to "Lionel Legacy Smoke unit takes out Boards"

I have gotten two Legacy locomotives, both with Canon motors, that the motor shorted and roasted the drivers on the RCMC. I was also of the belief that the RCMC had overcurrent protection, is there something about a direct short that it wouldn't deal with? Both motors measured a fraction of an ohm when I checked them, and they'd shutdown my 5A DC bench supply if I tried to run them from it. On the one RCMC I was successful at replacing the FET's, the other one had actually cooked the board and I just replaced the board.
