Hoseeker would have the literature but Rivarossi was never big on providing good diagrams in manuals. I have a cab forward same generation as the boiler-engine Big Boy and I think you will find the wiring straightforward once the boiler cover is off. Enjoy!
Ok i scored a rivarossi big boy mid 90s red box its the boiler motor so its isolated from tbe frame
I want to go from DC to DCC &install a decoder i had a wiring diagram on how to do itbut can't find it
Any help would be great ,hearing that loksound is the latest & greatest for heavy steam decoder??
