Thanks Bill, I think I can resolve the polarity issue with a 6 pole relay. Or I can just hook it up like it was in the BH.


Thanks Again,   Dale

Thanks Bill, the leads coming out of 2-8-0 are both black. The leads from the BH 4-6-0 don't indicate which is + or - does it matter? The connectors don't match so will be removing the one on the 4-6-0 sound card. This is just a temporary thing until I can put some better in but don't want damage 2-8-0.


Thanks again,   Dale

I have a g scale spectrum 2-8-0. With no sound. Can I take the sound module from a big hauler and install in my 2-8-0. If anyone has done this or something like it. Please let me know. The wiring diagram for the 2-8-0. Shows the 2 wire connector from loco is for sound. I assume this is for the chuff sensor.

Thanks
