I have an ERR CC that I had put in another engine last year and I was installing it into another engine. Last I had checked it worked fine. I installed it in the new engine and at first when I applied power the engine just took off. After about 2 times of doing that (while trying to isolate if there was a bad connection) it stopped and now the mosfets and bridge rectifier get hot and the breaker on my power supply trips. I have absolutely no indication as to why this might have happened other than I may have an issue with the pittman motor in my loco. Even now, when I unhook the motor 1 and motor 2 connections, the CC still gets hot but I don't see smoke or smell burning. Do you think the board may have gone bad? And if so, why? I'm all out of ideas and I loathe the idea of purchasing another one.
