MTH SD 35 Troubleshooting | O Gauge Railroading On Line Forum

I have a PS 3 MTH chessie SD 35 made several years ago. The engine consistently powers up when I apply power to the track when in a command control environment. The engine ignores the watchdog signal from DCS TIU and powers up. I have tried a factory reset but the problem persists. Any suggestions?

Check the DCC/DCS switch and make sure it's set to DCS.

good advice! That one caught me by surprise when I bought my first PS3 engine.

Wiring too close to board and under supercap can also cause this. Make sure caps folder over along board. Wiring harness goes over the caps.

Does it play shutdown sounds when power turned off? Bad supercap can also cause some issues. G
