My Acela saga continues. After replacing the Panto motor control board I placed the engine (#2026) the powered loco on my test track before I attached the shell. The loco and the panto worked fine. I secured the shell then put it on the test track again. As soon as I put power to it, I heard a pop and saw smoke. Well, the picture below shows what happened. For reasons I don't understand that black wire fried.(I have a suspicion I may have caused it to rub against the red wire when I was either taking the connector out or putting it in. It was a PITA. But, I'm not sure) I could not see any other visible 'damage.' I replaced the connectors with newly wired ones and it didn't help. The 8 pin connector runs from the motherboard to the switch control circuit board. I tried reprogramming and resetting...nada. Any ideas about what's wrong? I'm thinking the motherboard was damaged, but I don't know if it's also likely others are damaged. I'm prepared to replace all the boards...the sale is coming, but if there is a clear culprit...or, should I just write it off? Any help welcomed. Paul "The Acela fella" on the Forum has been very helpful.
