MTH 30-1162-1 RK K4 Proto 2 Once again I smoked out a DCS engine. I have cab 2 also and dcs both connected to the track. Didn't turn on the cab 2 The power to the dcs tiu was on. As soon as I turned on my DCS controller the smoke and blown noise happened This engine has a white 9v looking battery in the tender. What happened and why? What should have I done differently? Obviously I haven't learned my lesson since the last one I fried

You should have replaced the battery before trying to run it. That battery was around 20 years old. Very possible the bad battery overloaded the charging circuit and took out the board.

I've personally seen several 5V boards go up in smoke, and even one 3V board. As stated, that happens, especially with the older 5V boards.

I don't know that the battery caused the problem, but any of the 20+ year old white batteries should have been retired years ago!
