Hi everyone, I have a variant of the headlight dimming issue that I resolved a while back with your help on a 5V PS2 SF 4-10-2 loco. This time it is a MTH Premier J-1 Hudson (20-3059) 5V loco. In this case, it is the marker lights that dim, then blink as the engine starts up if the smoke is on. The blinking is synced to the speed such that at higher speeds, the blinking is not visible. I tried the "royal blue" grounding wire swap I did for the SF 4-10-2, but that made the problem worse. It appears that the fix  document I used for the SF engine did not seem to match the wiring or the DSC board layout of the Hudson. Is there another fix document that might apply to the Hudson? Or is there something else I should try?

Thanks and best regards,

Walter
