Reply to "2 rail TMCC & DCC Just Curious"

GGG, I'd assume as a repair tech you have access to schematics that I do not. I suppose it is possible such boards use a single diode to convert AC to DC. in either case the net result is the same, there is no path for electrons to take in reversed polarity, thus nothing that could be damaged. The only board schematics I could locate were on the TMCC manual thread and none of the boards mentioned were there. The most recent post shows the ERR sound converter which uses a single diode before a voltage regulator.

Anyway, I am very curious for technical information on any board in use, as well as technical information showing how DC current could damage any of these boards.
